[libvirt] [RFC] lxc.cgroup.blkio.weight_device automatic conversion
Hi all, I wish you all a happy new year 2014. I'm currently implementing connectDomainXMLFromNative for the LXC driver. The idea is to convert sourceforge LXC's config file into domain XML files. I just hit a problem with converting blkio device weights. LXC's config directly stores the cgroup value, defining the device with it's major and minor numbers. It seems to me that there is no way to get a path from these numbers, so what would you think about extending _virBlkioDevice to store either a path or a major/minor pair and extend the domain XML schema accordingly? Regards, -- Cedric

I found out that /dev/block/major:minor could do the trick... I'll start with that... unless someone feels it's a bad idea. -- Cedric
