Well, when sda2, on which is the /boot/ partition is now sdc2, that looks kind of aproblem to me when the os quits its ramdisk.
And with 3 NICs, two of which are 1Gb/s able and one only 100Mb/s, when eth0 becomes eth2, all the virtual machine lack a bit of bandwidth. If you see what I mean.
thats why we use UUID pointing to the boot partition instead of /sdx ...
Code:
cat /etc/fstab
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/pve/root / ext3 errors=remount-ro 0 1
/dev/pve/data /var/lib/vz ext3 defaults 0 1
UUID=c256ea93-bc9a-42de-83cc-56f10c1f2d6d /boot ext3 defaults 0 1
/dev/pve/swap none swap sw 0 0
proc /proc proc defaults 0 0
