Re: [libvirt-users] Libvirt Error guest wont start



I figured it out. Apparently someone else ran some updates on the host machine and the distro version of QEMU was installed and libvirt was finding that one instead of the updated QEMU that was previously installed. Thanks for the help!

Could you check 'virsh dumpxml guest0 | grep emulator' and check what's
the qemu being ran by libvirt?  Then take that path and run it with
'<binary> -M ?' and check if the 'pc-1.1' is there.  To fix your issue,
try 'virsh edit guest0' and change the 'pc-1.1' to 'pc'.
