Question about KVM domain not available on trusty
I forgot, on trusty, qemu-kvm doesn't exist as is, and when I try to create a template I get errors like: libvirt: QEMU Driver error : unsupported configuration: Domain requires KVM, but it is not available. Check that virtualization is enabled in the host BIOS, and host configuration is setup to load the kvm modules. So 2 issues there - in trusty get a proper qemu version to avoid messages error: internal error: process exited while connecting to monitor: Warning: Disabling some instructions which are not emulated by TCG (0x0, 0x4) qemu: hardware error: qemu: could not load LPAR rtas '(null)' - in kimchi, detect if kvm not a valid domain type then use qemu Does that sound an issue ? - do you want me to code that ?

When kvm will not be a valid domain? Some dependency on package version?

yes - on trusty there is no qemu-kvm package by default and virsh capabilities show the domain type for arch ppc64 as qemu only - on utopic it shows kvm and qemu. The issue is the same for x86_64 arch. The question would be - should we use what'is in the release and adapt kimchi for it or should be build what's needed for the product to work ? Thanks

On x86_64, I get: # kvm-ok INFO: Your CPU does not support KVM extensions KVM acceleration can NOT be used and virsh capabilities <guest> <os_type>hvm</os_type> <arch name='x86_64'> <wordsize>64</wordsize> .... <machine maxCpus='255'>pc-0.13</machine> <domain type='qemu'> </domain> </arch> <features> <cpuselection/> <deviceboot/> <disksnapshot default='on' toggle='no'/> <acpi default='on' toggle='yes'/> <apic default='on' toggle='no'/> </features> </guest> On 02/09/2015 09:30 PM, Thierry Fauck ( thierry @ linux.vnet.ibm.com ) wrote:

Ok - I am OK to switch to qemu when kvm is not present but the default must continue to be kvm. You can use conn.getCapabilities() to get the available options for that according to arch.
