vmbuilder, virtio and fstab

nic@vm-base:~$ sudo blkid /dev/vda2
/dev/vda2: UUID=”0c75b2dd-6c6f-4729-b041-0d95475dc171″ TYPE=”swap”

If you install a vm with vmbuilder without virtio the swap section of /etc/fstab will use /dev/sda2 instead of /dev/vda2. You can use blkid

nic@vm-base:~$ sudo blkid
/dev/vda1: UUID="bac299c4-c545-46ca-aed3-26da4a56f6d7" TYPE="ext3"
/dev/vda2: TYPE="swap" UUID="0c75b2dd-6c6f-4729-b041-0d95475dc171"
/dev/vdb: UUID="jIkLcQ-zXUo-KIWR-zvmm-cpKP-9PpT-eE9RY3" TYPE="lvm2pv"
and then add this UUID to fstab:
nic@vm-base:~$ cat /etc/fstab
# /etc/fstab: static file system information.
# <file system>                                 <mount point>   <type>  <options>       <dump>  <pass>
proc                                            /proc           proc    defaults        0       0
/dev/sda1                                       /               ext3    defaults        0       0
UUID="0c75b2dd-6c6f-4729-b041-0d95475dc171"     swap            swap    defaults        0       0

in order to get swap working with different driver types.

Running KVM

I’ve started running KVM recently and I’ll post a review at some point. I’m finding it very flexible and much much easier to use that Xen.

There are still a few questions regarding file caches and disk images. In general I’m happy that it’s ready for production.

Sun and IBM

I haven’t seen much yet to confirm this deal, but if it does happen next week it mark an interesting change in course.  The thing that would interest me greatly would be zfs on linux – with Sun owned by IBM and their investment in Linux it might lead to a reconcilation between Sun and Linux licenses.  While Solaris has come a long way in the last couple years, but the only reason why I use solaris is zfs.  Linux is still a much more flexible, effective and deployable solution.
