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

[Serge Hallyn]

@Luke,

thanks for the information.  Just to be sure, your symptoms are exactly
the same as in the Description - kvm hangs (no response to network or
the vnc console) and takes 100% cpu?

Unfortunately, based on your .xml file it looks like you're not using an
LVM backed VM.   I wonder if we should pursue this in a separate bug.
Would you mind opening a new bug?

If you could install the libc debugging symptoms and reproduce that
could definately help.  It would be good to figure out why select is
hanging.  If possible, getting the list of arguments passed to select
from gdb and comparing the list of fds to /proc/<pid>/fd/<n> entries
could also help.

If you change your machine type to pc-1.1 or pc-0.12, or change the
network device type and/or switch to using the default virbr0 network,
does that help?

Is there anything in your host's syslog which looks helpful?
