[Bug 577027] [NEW] unable to ssh to guest vm after volume attach

[Jason Rogers]

Public bug reported:

Binary package hint: qemu-kvm

Description:	Ubuntu 10.04 LTS
Release:	10.04

kvm:
  Installed: 1:84+dfsg-0ubuntu16+0.12.3+noroms+0ubuntu9
  Candidate: 1:84+dfsg-0ubuntu16+0.12.3+noroms+0ubuntu9

I had a guest vm running on a eucalyptus cloud using virtio for disk and
network I/O. I also had an ssh session on the guest vm. When I attach a
volume to the instance using euca-attach-volume I lose network
connectivity to the guest.

Before I upgraded to lucid I was running karmic, and there was no issue.
After the upgrade, I started having issues.

I've tried the UEC 9.04, 9.10 and 10.04 i386 images, along with some
custom amd64 images that worked previously under karmic.
