[libvirt] virsh -no-kvm problem on debian install
Hi,
i've installed lastest kvm-86 and libvirt-0.6.4 tarballs on my debian
stable and have a problem using virsh
No matter what i do in the guest domain config or with /usr/bin/
symlinks, libvirt keeps using the -no-kvm option when starting guests
when my cpu has kvm-amd support, modules are loaded and /dev/kvm exists,
and starting the guests thru command line works fine, and faster.
debian seems to install the following binary
/usr/bin/qemu-system-x86_64, i had to add "/usr/bin/qemu" to get virsh
to work, otherwise it will say it can't connect to qemu:///system
here's some command output :
#virsh -c qemu:///system capabilities
<capabilities>
<host>
<cpu>
<arch>x86_64</arch>
</cpu>

and tried adding "/usr/bin/qemu-kvm" symlink

So far i had no luck getting virsh to use kvm, it always adds the
-no-kvm option, i'm not sure how to specify the domain type in the guest
config, using the <emulator>/usr/bin/qemu-kvm</emulator> won't help.
i've found that thread discussing the binaries and options but don't
know if that patch was already added or if i have to patch my tarball..

please let me know if there's some way to let libvirt know that kvm
exists on a debian install, using /usr/bin/qemu-system-x86_64
thx,
