Which kernel is the host running and which kernel is the guest running? And which kernel has the vsyscall=emulate parameter? If vsyscall=emulate is a problem on a pre-3.3 kernel, can you try something containing commit 4fc3490114bb159bd4fff1b3c96f4320fe6fb08f? (UML, for example, is known to have serious issues without that fix.) Otherwise, can you tell me what hypervisor you're using and what init version (i.e. the rpm) so I can try to reproduce it? A pointer to an actual image would work, too. A copy of the oops would also be nice. --Andy -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
