Hi Dave-

I just uploaded qemu-kvm 0.12.3 to Lucid, which includes a number of
storage fixes, according to the changelog.  It would be great if you
could give that a test run and report back!

** Description changed:

  Binary package hint: qemu-kvm
- (This may be #420423 but we're running a much newer kernel on lucid).
+ (This may be  Bug #420423 but we're running a much newer kernel on
+ lucid).
  Host: Lucid 64bit uptodate as of 23rd January - i7-860  - 2.6.32-11-generic #15-Ubuntu
  qemu-kvm: Version: 0.12.2-0ubuntu1
  Guest: lucid alpha 2 64bit iso (having pressed update-installer on it on
  23rd Jan).
  Symptom: During install at a non-repeatable point the root filesystem of the guest becomes RO
  and there are dmesg logs on the guest says that there were write errors on vda1.  The block numbers
  are different on repeated installs.
  There are no errors on the hosts dmesg.   The disc is backed by a lvm
  lv, and I've tried writing it with dd if=/dev/zero
  of=/dev/main/fiddle2disk bs=1024k and the whole disc writes OK.

** Changed in: qemu-kvm (Ubuntu Lucid)
       Status: Confirmed => Incomplete
