Hi there,
we have a persistent problem with Ubuntu as a DomU.
Despite the fact that it has libc6-xen libraries installed and /lib/tls
moved aside, we still get these sorts of message:
4gb seg fixup, process init (pid 1), cs:ip 73:b7e1b236
stevew@hostname:~$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=6.10
DISTRIB_CODENAME=edgy
DISTRIB_DESCRIPTION="Ubuntu 6.10"
stevew@hostname:~$ uname -a
Linux biotech-ubuntu 2.6.18-3-xen-686 #1 SMP Mon Dec 4 20:48:20 UTC 2006
i686 GNU/Linux
stevew@hostname:~$ ldd /sbin/init
linux-gate.so.1 => (0xb7fbb000)
libc.so.6 => /lib/libc.so.6 (0xb7e94000)
/lib/ld-linux.so.2 (0xb7fbc000)
There is no file matching linux-gate* on the system.
Any ideas?
Thanks!

Can''t say I know what that is. I had too many problems trying t get 6.10 running as host and guest. So I used Ubuntu 6.06 and compiled Xen 3.0.4 from source with no problems at all. Gave up on xen binary packages in Ubuntu for my 64bit Ubuntu. Very stable on my AM2 3800X2 with 6.06 and Xen 3.0.4.

Not sure how to fix it myself (64-bit is my great friend), but it''s been discussed to death here before, so Google Should Provide. - Matt _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I see this on my ubuntu domUs also, I don''t use initrds and I do have libc6-xen installed. I only see it for init (pid 1) and don''t seem to experience any slowdown. So basically I was under the impression that seeing this for init is expected and harmless. Is this not the case?

Is this not the case?mkinitramfs just copies everything over from /lib from wherever you ran it. So , if you built the initrd prior to installing xen glibc, then you have the old version on your initrd. It will throw a warning either way. Probably safe to ignore.
