[Bug 1029889] Re: LVM Based KVM VM taking 100% CPU on first start and hangs.

[Luke Randall]

Sorry for not responding for so long.

takes 100% cpu?

Yes, the symptoms are exactly the same.

an LVM backed VM. I wonder if we should pursue this in a separate bug.
Would you mind opening a new bug?

I've experienced the exact same bug (or at least the exact same
symptoms) both with LVM and qcow2 images. If you feel that LVM is a
sufficiently differentiating factor then I'm happy to file a new bug.

I've found that two out of three servers with 12.04 are affected by this
bug. That means that brand new images built on these machines exhibit
this bug. However, I am still able to build images on the third server
which work as expected on any of the three servers. I don't know what to
make of that, since the machines should be close to identical in setup
(and are certainly identical from a hardware perspective).
