You don't need +xsave, -cpu host just works. The bug is invalid. You are requesting a CPU that doesn't exist (a core2duo that supports XSAVE), and the guest's behavior is probably not going to be well defined. ** Changed in: qemu Status: New = Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1285708 Title: FreeBSD Guest crash on boot due to xsave instruction issue Status in QEMU: Invalid Status in qemu-kvm: New Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Precise: Won't Fix Status in “linux” source package in Trusty: In Progress Bug description: When trying to boot a working FreeBSD 9.1/9.2 guest on a kvm/qemu host with the following command: kvm -m 256 -cdrom FreeBSD-9.2-RELEASE-amd64-disc1.iso -drive file=FreeBSD-9.2-RELEASE-amd64.qcow2,if=virtio -net nic,model=virtio -net user -nographic -vnc :10 -enable-kvm -balloon virtio -cpu core2duo,+xsave The FreeBSD Guest will kernel crash on boot with the following error: panic: CPU0 does not support X87 or SSE: 0 When launching the guest without the cpu flags, it works just fine.

[Kernel-packages] [Bug 1285708] Re: FreeBSD Guest crash on boot due to xsave instruction issue
Quite right - our workaround was to switch to using the host capabilities instead of the compatibility fallback. However, the decision for a compatibility fallback was automatically made and included the above combination. I don't know where that bug should sit. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1285708 Title: FreeBSD Guest crash on boot due to xsave instruction issue Status in QEMU: Invalid Status in qemu-kvm: New Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Precise: Won't Fix Status in “linux” source package in Trusty: In Progress Bug description: When trying to boot a working FreeBSD 9.1/9.2 guest on a kvm/qemu host with the following command: kvm -m 256 -cdrom FreeBSD-9.2-RELEASE-amd64-disc1.iso -drive file=FreeBSD-9.2-RELEASE-amd64.qcow2,if=virtio -net nic,model=virtio -net user -nographic -vnc :10 -enable-kvm -balloon virtio -cpu core2duo,+xsave The FreeBSD Guest will kernel crash on boot with the following error: panic: CPU0 does not support X87 or SSE: 0 When launching the guest without the cpu flags, it works just fine.

[Kernel-packages] [Bug 1285708] Re: FreeBSD Guest crash on boot due to xsave instruction issue
Testing with the identified patch doesn't solve the issue, in addition looking at the cpu flags (core2duo +xsave) this may not be a valid configuration since xsave assumes additional features will be there (instead of creating an older cpu model with xsave.) Therefore I believe this is a configuration issue. The comment above in #4 assumes your host has the correct cpu features, you can always run something like: kvm -cpu host,+xsave,check to check if are issues with the host plus additional features settings. In addition I've been able to use '-cpu SandyBridge,+xsave' and this also works. Marking this 'Won't Fix' as there is a clear workaround (use another CPU model), and this configuration may not be valid.

[Kernel-packages] [Bug 1285708] Re: FreeBSD Guest crash on boot due to xsave instruction issue
Thanks for reporting this bug. Given the lkml.org fix, I assume this is in fact a kernel bug, so assigning it as such. This is presumably fix-released in utopic, but SRU-able to precise and trusty's backport kernels. I'm not clearn on how that process works, so leaving it like this. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** No longer affects: qemu (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1285708 Title: FreeBSD Guest crash on boot due to xsave instruction issue Status in QEMU: New Status in qemu-kvm: New Status in “linux” package in Ubuntu: New Bug description: When trying to boot a working FreeBSD 9.1/9.2 guest on a kvm/qemu host with the following command: kvm -m 256 -cdrom FreeBSD-9.2-RELEASE-amd64-disc1.iso -drive file=FreeBSD-9.2-RELEASE-amd64.qcow2,if=virtio -net nic,model=virtio -net user -nographic -vnc :10 -enable-kvm -balloon virtio -cpu core2duo,+xsave The FreeBSD Guest will kernel crash on boot with the following error: panic: CPU0 does not support X87 or SSE: 0 When launching the guest without the cpu flags, it works just fine.
