@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? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1029889 Title: LVM Based KVM VM taking 100% CPU on first start and hangs.
