[Bug 956051] Re: libc6 crash while running 'xm'

[Tom Worley]

Can I ask that the Precise fix gets put into 12.04.1 LTS as at the moment the 12.04 LTS installer will not install on XenServer, this would make a big difference rather than having to try and install 11.10 and then upgrade (if the correct package will be used in the upgrade).
This is quite an urgent issue for Xen/XenServer/XCP users meaning that the LTS edition can't be used on a very large range of servers and virtual machines either by installing it directly or by upgrading.
Thanks very much.
Regards,
Tom Worley

Title:
  libc6 crash while running 'xm'

Status in “eglibc” package in Ubuntu:
  Fix Released
Status in “eglibc” source package in Precise:
  Confirmed

Bug description:
  Ubuntu Version: 12.04 (precise)

  libc6: 2.15-0ubuntu5
  xen-hypervisor-4.1-amd64: 4.1.2-2ubuntu2
  linux-image-generic: 3.2.0.18.20

  Everytime I try to run 'xm list' on a new AMD Opteron 6274 system (Bulldozer architecture) I'm getting a crash.
  I couldn't even file a bug report through "apport-bug".
  Repeating the same procedure with Ubuntu Oneiric showed no problems at all.

  dmesg showed following messages:
