Re: [ovirt-users] Qemu prevents vm from starting up properly
Hello!
Thank you very much! I had misunderstood how it was suppose to be
written in qemu_cmdline. There was a typo in syntax and error log
revealed it. It is working IF I use ["-spice",
"tls-ciphers=DES-CBC3-SHA"].
So I believe that installation is correctly done.
Though, my problem still exists.
This is what I have been trying to use for qemu_cmdline:
["-cpu", "kvm=off, hv_vendor_id=sometext"]
It does not work and most likely is incorrectly written.
I understood that qemu commands are often exported into xml files and
the command I'm trying to write is the following:
<features>
<hyperv>
<vendor_id state='on' value='customvalue'/>
</hyperv>
<kvm>
<hidden state='on'/>
</kvm>
</features>
How do I write this in custom properties for qemu_cmdline?
best regards
Mikko

Please check/share /var/log/libvirt/qemu/* and /var/log/vdsm/* . Thanks.
