Subject: [GIT PULL] Linux KVM tool for v3.7-rc0

Hi Linus,

Please consider pulling the latest LKVM tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/penberg/linux.git kvmtool/for-linus

LKVM is the long lost userspace friend of KVM that makes it really easy
to launch virtualized Linx environment on x86 and PPC64 Linux.

To try out LKVM, first make sure you have a KVM and virtio enabled
kernel:

make defconfig
make kvmconfig
make

Second, install LKVM to your $HOME/bin directory:

make -C tools/kvm install

And then simply type:

lkvm run

and you are greeted with a network-enabled shell in a KVM sandbox using
your host binaries running a freshly built kernel.

One really cool thing to do with LKVM is run Trinity. the Linux syscall
fuzzer, in a KVM sandbox.

To do that, first fetch latest Trinity sources and install it to your
$HOME/bin directory:

git clone git://git.codemonkey.org.uk/trinity
make -C trinity install

Then start trinity in a KVM sandbox:

lkvm sandbox -- $HOME/bin/trinity --dangerous

Pekka

This still doesn't have any business in the kernel tree. I also can't
remember than any new arguments came up why this should be merged vs
the arguments why it's been reject over and over again.

So you have not taken this in the v3.7 merge window.

Will you ever merge this? If not, it should be removed from linux-next
(where it has been sitting since before v3.1) and turned into an
independent (to the kernel) project.

I have yet to see a compelling argument for merging it. It's tons of
code, it doesnt match the original "small simple" model, and I think
it would be better off as a separate project.

Pekka & the LKVM developers are using the tools/kvm/ tree setup
to create new kernel features, to improve the kernel and to
reuse kernel code, amongst other things.

So being in the kernel tree is very practical and useful to
them.

It's also *very* useful to kernel developers like me, and I wish
all of user-space tooling was as easy to use and as well working
as 'vm run':

I'm using 'vm' regularly for quick kernel testing: I just want
something that just works and reuses the existing distro
user-space environment unintrusively. In that sense it's very
handy, 'vm' will in essence boot the well-maintained system. Not
some stale old disk image. Not a second system I need to
maintain. I'd not be using it if it didn't came integrated via
tools/ and integrated into the kernel. 'make kvmconfig' and the
other bits of practical kernel development integration are very
useful and just work as well.

The fact that it's not useful to you (yet?) that does not
invalidate the utility of this project to those to whom it *is*
useful. No argument you ever outlined here invalidates the plain
utility of this project.

Whether you think that it "has no place in the kernel" is
completely irrelevant - what matters is actual utility to
people:

If Linus thinks that the upsides are not convincing enough (yet,
or ever), that's obviously enough reason for him to not pull it
- but that does not stop this project from being useful to those
who *are* using it to improve and test the kernel.

Thanks,

Ingo

It's probably not a surprise to anyone that I'm with Ingo on this. It's
OK if people don't think tools/kvm is *worth it* but claiming that living
in a separate repository is just as easy is completely ignoring reality.

So are there any compelling arguments from the proponents, or can I
remove this from linux-next (and have it removed from the tip auto-latest
branch)?

FWIW, I gave this a run and I have to say, it works as advertized: I
built it and ran it with the latest kernel and the thing simply boots
the kernel. Even without a disk image - the simplest command is:

$ ./lkvm run --kernel ../../arch/x86/boot/bzImage

and it gets me a shell in the vm after a second.

So the absolute advantage it gives kernel devs is that they can
smoke-test whether their stuff boots in seconds.

This is probably not helpful when enabling specific hw features but
should be pretty helpful for generic arch stuff.

HTH.

Why couldn't this script just be a wrapper around qemu?

I get the kvm developers developing features that isn't ideal, but for
the quick boot a kernel tests, I don't see why a well maintained qemu
wrapper isn't superior. I hate constructing qemu command lines, but a
script in the kernel repo seems like a good idea.

you can build one iso like:

make isoimage FDARGS="ignore_loglevel debug initcall_debug
acpi.debug_layer=0xffff0000 pci=routeirq apic=debug
ramdisk_size=262144 root=/dev/ram0 rw ip=dhcp
console=uart8250,io,0x3f8,115200"
FDINITRD=/home/yhlu/xx/xx/rootfs/mydisk14_x86_64_xz.xz

then use kvm to load that iso

/usr/local/kvm/bin/qemu-system-x86_64 -L /usr/local/kvm/share/qemu -m
6144 -net nic,model=e1000,macaddr=00:1c:25:1c:13:e9 -net user -smp 2
-cdrom /home/yhlu/xx/xx/kernel/tip/linux-2.6/arch/x86/boot/image.iso
-boot d -serial telnet:127.0.0.1:4444,server -monitor stdio

later could use
telnet 127.0.0.1 4444
in another terminal to get serial console.

and initrd is converted from opensuse rescue initrd.

hope we can have scripts to create standalone initrd with updated user
program etc.

Well, Alex Graf had exactly that but I don't know what happened to it -

Every kernel developer has his own wrapper script to make qemu usable.
IMHO it's time to add such a script to the kernel tree.

You are wrong on three counts:

- As I mentioned it in my first mail to you this is not the
same as 'vm run': you still have a qemu-root.img while
tools/kvm does not ...

'vm run' works without having any disk image around, it just
uses the existing distro binaries and boots them, sharing the
host file system.

- automatic, transparent host filesystem sharing is another
useful feature: I can copy files in/out of the virtual
machine using the host filesystem.

- transparent networking is up and running straight away

But yeah, I guess if you ignore enough key tools/kvm/ features
then you will eventually be right: it's really just the same as
Qemu and has no place in the kernel repo ;-)

Ingo

qemu supports all these features.
E.g. to access the host fs use:
qemu ... \
-fsdev local,security_model=passthrough,id=fsdev-root,path=/your/root/,readonly
\
-device virtio-9p-pci,id=fs-root,fsdev=fsdev-root,mount_tag=rootshare

The best way to compare them would be a script that gives
exactly the same test environment that 'vm run' / 'vm sandbox'
does out of box, but using qemu.

If such a script is available then that would certainly be a
useful testing option to kernel developers.

IIRC, QEMU uses SLIRP non-root zero-config networking which is much
more limited than what LKVM offers out of the box.

Using host system rootfs is not quote as simple as you seem to think
so you need something like Alexander Graf's shell script for
comparable 'vm run' experience.

Right,

I gotta say, I've mucked around with qemu/kvm net options as a novice
user and haven't always been successfu. If you get host networking
straight away in lkvm then that's another clear point for tools/kvm.

Same holds true for copying data back and forth between host and guest.

Thanks.

I'm agnostic about lkvm, but the following command does all the above:

qemu-system-x86_64 -enable-kvm -net nic,vlan=0,model=virtio -net user -fsdev local,security_model=passthrough,id=root,path=/ -device virtio-9p-pci,id=root,fsdev=root,mount_tag=/dev/root -m 512 -smp 2 -kernel /usr/src/linux/arch/x86/boot/bzImage -nographic -append "init=/bin/zsh root=/dev/root console=ttyS0 kgdboc=ttyS0 rootflags=rw,trans=virtio rootfstype=9p ip=dhcp"

If you want your host root-fs to be mounted rw (to copy data back and forth)
you need to run to above as root and add "rw" to the kernel options.

Why does it have to run as root? I run 'vm' unprivileged (other
than /dev/kvm access).

>From the qemu man page:

security_model=security_model

Specifies the security model to be used for this export path. Supported
security models are "passthrough", "mapped- xattr", "mapped-file" and "none".
In "passthrough" security model, files are stored using the same credentials as
they are created on the guest. This requires QEMU to run as root.

But you can use security_model=none as an unprivileged user. With this
option you can only change files for which you have permission (like
in your home directory).

So I guess running it with 'none' can be used unprivileged?

That's very much desired for testing anyway.

Ok, looks useful - will someone on the Qemu side script this up
and integrate it into the kernel in a useful form?

One observation I'll make is that for many people, what you want to do
is a *lot* more than just simply create a wrapper script to fire up
qemu. For me to do my testing, I want to build a kernel on the host
OS, and then fire up a script which fires up xfstests and runs it with
a collection of different file system mount options to do my ext4
testing. I've shared that here:

git://git.kernel.org/pub/scm/fs/ext2/xfstests-bld.git

where the host-side scripts are in the kvm-xfstests directory, and the
guest-side scripts are in the kvm-autorun directory. I can pass in a
set of fs configurations and xfstest test numbers via the command line
on the host os, i.e., "kvm-xfstests -c 4k,ext4,nojournal
13,225,245,246". And then afterwards the scripts parse out the test
output and summarizes so it's easy to see what passed and what failed.

So the bottom line is that for me at least, starting up qemu is a very
tiny part of what I need to do in order to do my testing. If you want
to really encourage good testing, what would be better is to encourage
more people to create standardized testing and benchmarking scripts
that many kernel developers can easily run. And those are going to be
complex enough that I don't think it makes sense for them to live in
the kernel tree.

There are going to be as many options as there are users - people will
want different things, like block device assignment (for fs/iosched
people), device assignment (driver developers), cpu/memory topology, or
a dozen other things. I think the best we can hope for is an example
script for people to copy and modify, otherwise we'll end up with the
same number of options that qemu has.

Me too, especially as we discussed replacing SLIRP with lkvm code for
userspace networking and decided (for reasons I do not remember) that it
lacks futures SLIRP has. Was it host port redirection?

Yes. Currently, there is no host to guest port forward support in lkvm.
However, it's faster than slirp.
e.g. tcp bandwidth in a 100Mb/s environment
lkvm's userspace networking ~90Mb/s v.s qemu's slirp ~10Mb/s

This is not entirely slirp fault BTW. If you run QEMU with "-usbdevice tablet", slirp
bandwidth goes up to 80-90Mb too.

So, where did we get to? I *think* the consensus was that the KVM tool
did not need to be in the kernel tree, right? In which case:

1) I need to remove the kvmtool tree from linux-next
2) the same code needs to be removed from the tip tree

hmm?
