Subject: [Qemu-devel] [Bug 1285708] Re: FreeBSD Guest crash on boot due to xsave instruction issue
Date: Wed, 06 Aug 2014 16:56:57 -0000 [thread overview]
Message-ID: <20140806165657.21032.5777.malone@soybean.canonical.com> (raw)
In-Reply-To: 20140227150100.32637.87688.malonedeb@gac.canonical.com
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.
Thanks

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.
This bug has been resolved in source:
https://lkml.org/lkml/2014/2/22/58
Can this fix be included in Precise ASAP!
