[Users] Manage KVM/Qemu and OpenVZ the same way

[Bosson VZ]

Hi,

the driver supports vSwap AFAIK. You can set RAM limits (soft, hard) and SWAP hard limit (soft is always 0). Could you explain to me what you mean by vRaw?

I understand that vzctl provides a lot of knobs to play with but since libvirt is supposed to be a common management interface, I had to play by the libvirt rules. I extended the libvirt XML syntax only as much as was needed for supporting the amount of features that we use at the company. I also didn't want break too many things and sticked with the semantics that was already in libvirt for LXC.

UBC settings is currently reduces to only manage RAM and SWAP. All other UBC limits are set as unrestricted. Technically, it is not hard to extend the driver to support all the UBC limits but I don't want to divert from the upstream libvirt domain file syntax too much.

Ploop is not supported as we don't use it in the company. Most of the features that ploop provides can be easily achieved with LVM/drbd. However, unlike the UBC limits, there is already a syntax for "mounting a file as a file system" in libvirt, so implementing ploop might be possible.
