Ubuntu 12.04 LTS fails to install on XenServer 6.0.2

[Ryan Cresawn]

I am unable to install Ubuntu 12.04 LTS (server amd64) on XenServer 6.0.2. The error message below is found in /var/log/syslog after the installation process aborts. I am able to reproduce this.

Hi,
I've exactly same problem with Dell R715 + Dell Equallogic ps4100xv

[Ryan Cresawn (jrcresawn)]

I have three servers running XenServer 6.0.2. Two are Dell PowerEdge R815 servers and one is a Dell PowerEdge 2950. The 2950 has an Intel Xeon 5130 processor and the R815 servers each have four AMD Opteron 6274 processors. I see David that your R715 has an AMD processor. I created a virtual machine running Ubuntu 12.04 on the 2950 and it works fine. Now I have new questions.

Is the AMD Opteron 6274 processor the reason I can't install Ubuntu 12.04 on XenServer 6.0.2?
Is this an Ubuntu 12.04 problem?
Is this a XenServer 6.0.2 problem?

I just found this forum post which seems very likely related.

This bug is unique to the Opteron 6200 series processors.

Hi Ryan,
you have right
no problem with R415 and AMD Opteron(tm) Processor 4176 HE...

there is no problem with other vm deployment like debian, seems only ubuntu is concerned.

Same problem with Dell poweredge R515 (dual opteron 4226)

help please....

[Ubuntu Bugs (ubuntubugs-ramihyn)]

This bug is NOT unique to Opteron 6200 series processors, i have the same problem on my FX-8120.

There obviously is an updated glibc with this bug fixed, but its in the "precise-updates" repo, not in "precise". Too bad that debootstrap downloads from "precise" only.

The only solution would be to put the updated glibc in "precise", may it be frozen or not - else debootstrap still will be non-functional under Xen, when the "Long Term Support" runs out.

Hi, Previous reports and bug fixers

I am caught by this bug since this summer.

My server is HP DL165, which is using AMD Opteron 6220

This bug seems Ubuntu specific. This summer I tried ubuntu 10.04/12.04 on Xenserver 6.02 and never succeeded, but centos works.

Today I tried ubuntu again on Xenserver 6.1, Now the status is
Ubuntu 10.4 64bit works
ubuntu 12.04 32bit works
ubuntu alternative 12.04 64bit works

But ubuntu 12.04.1 Server 64bit still failed.

Questions:

How did the previous report get the system log in Xenserver?

When will the patch go into Ubuntu Server 12.04 64bit?

Thanks.

Workaround: download ubuntu 12.04.3 iso, mount it and create image from iso:

wget http://releases.ubuntu.com/12.04.3/ubuntu-12.04.3-server-amd64.iso

mount ubuntu-12.04.3-server-amd64.iso /mnt/

you have to fix /usr/lib/xen-tools/karmic.d/20-setup-apt because it tries to recieve updates from given mirror:
