I'll reiterate that this isn't ideal, but it's the best balance of security and convenience that I've found so far. However, even if we fix this, SELinux will balk about three additional issues and we'll need to adjust the contexts on every new fixed block device we make.

If you are running 64-bit I advise Xen 3.2 as it will allow 32-bit domUs on 64-bit dom0 to work properly, but unfortunately you will need to compile it from xen.org's

You can by the way convert this existing setup to iSCSI by turning these 2 servers into iSCSI targets and exporting the /dev/drbd0 PV on each to say Xen blade servers
You will need to do this with Xen 3.2 as I do not believe that RH/CentOS libvirt will migrate the VM config! elif disk.uname.startswith('drbd:'): #get the drbd device associated with this resource drbdres = re.match("drbd:(.*)", disk.uname).group(1) drbddev = util.runcmd("drbdadm sh-dev %s" % drbdres).rstrip() #check for remus supported drbd installation rconf = util.runcmd("drbdsetup %s Find out what you can do.
