Description AL13N 2013-03-07 21:52:49 CET

virt-manager apparently uses blktap, which we have disabled in our builds, since it's a special kernel-patch/driver.

we could add it to our kernel servers (or make a specific dom0 server build)

but, it's been superseeded to blktap2 (even though no other distro has it yet), (which virt-manager doesn't use anyway).

and there's also qdisk (which is qemu-compatible), but qdisk is highly experimental. (ie: i didn't get it to work)

but, it's deemed more efficient to use lvm directly (then you don't need blktap), except that virt-manager seems to do that anyway (or it's maybe libvirtd that decides this...; whichever one makes the xml file to start up a machine)



i think that: adding blktap would be the easiest way to get things going with virt-manager, but it's not really worth the hassle of getting it in there.

or, we can try to patch virt-manager to either have a "configurable backend type" or we use direct physical devices... (which will be slow if you have file images and fast if you use lvm storage)

well, it's likely that making an xml file and using virsh would likely work, but i don't know enough about libvirt to make such an xml file just yet...

and since i can't install one with virt-manager, i can't use the xml to look at it... (it doesn't show the xml it tries in the logs)

Sorry, but this bug saw no action since over 2 yrs ago. 
No cauldron package has stayed the same since then.

Closing as OLD

Please reopen if this report is still valid for _current_ cauldron and/or fully
updated Mageia 4

Status: NEW => RESOLVED
Resolution: (none) => OLD

i don't know anymore if virt-manager has changed enough for libvirt-xl to work well, but maybe we should just have blktap v2.5 which still seems to be the best one, since blktap3 is xapi only, and i tried getting xapi to work well, but it's too much embedded bundles really...

anyway, maybe dmks-blktap would at least get more efficient disk backend for virtualisation...

AFAIK: It would be more working out of the box with xen en virt-manager if we had this...
