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? <domain type='kvm'> <name>vm1</name> <uuid>ea14abdc-12a4-48cb-1424-46cdf15405f4</uuid> <memory>524288</memory> <currentMemory>524288</currentMemory> <vcpu>1</vcpu> <os> <type arch='x86_64' machine='pc'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='disk'> <source file='/kvmimages/vm1.qcow2'/> <target dev='vda' bus='virtio'/> </disk> <interface type='bridge'> <mac address='54:52:00:0a:dc:10'/> <source bridge='br0'/> <model type='virtio'/> </interface> <serial type='pty'> <source path='/dev/pts/1'/> <target port='0'/> </serial> <console type='pty' tty='/dev/pts/1'> <source path='/dev/pts/1'/> <target port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> </devices> </domain>
