Hi,
Got my git/hg builds of libvirtd/virt-manager running together with kvm.
Took some time but finally think I'm getting the
hang of it.
I noticed two things going from my pre-packaged Debian packages.
The older xml files I had seemed to generate a faulty kvm cmdline:
<disk type='file' device='cdrom'>
<target dev='hdc' bus='ide'/>
<readonly/>
</disk>
This seems to translate into a -drive file=,... The file argument for kvm
may be empty but should then not be defined:
"If you don’t specify the "file=" argument, you define an empty drive". As a
result the first vm I tried to start came back
with a message saying it could not open the diskfile.
Additionally, check below screenshot; the vm names appear to be missing.
Here's the complete XML of one vm,
did anything change coming from this one?
