Re: [Xen-users] Segmentation Fault

Hello,
I am running a server having 5 guest domains. Few days ago everything is
going fine but i needed to recompile the kernel of the guest domain (xenU)
for iptables supports in the kernel.
When i issued the command 'make menuconfig' the result is nothing but
segmentation fualt
I have run the memtest also but memtest is good. Now the situation is that
the system is not allowing me to compile, install or upgrade any thing,
even on cp or mv commands, the segmentation fault is coming.
Could your guest domain have been *hacked*, by a cracker? Can you shut
down the Xen guest domain and do a "chroot" to the mounted file system,
and see if anything works? Or are you running from
Also the xend service is not running, when i try to start this service the
system goes to waiting state and needed to stop the issued command.
Wait. xend runs only on the server, Dom0, not on DomU. Did you put the
new kernel on Dom0, or are you using pygrub or its like to boot a local
kernel on the guest domain?
Also on the boot the eth0 is not coming up. ifconfig is showing me only lo
interface. So every time it requires assigning the network settings (ips).
And when the network settings are applied, the eth0 came up and works.
This sounds like you compiled on top of and overwrite the system kernel
on Dom0.
Any body has pointers to this problem. I have searched the mailing list
but not found any feasible solution.
The server has CentOS4.4 installed and also the guest domains.
The xen version is 'xen-3.0.2'
Well, upgrade to CentOS 4.5. then, stop compiling your own kernels
unless you're comfortable with that sort of thing and stick with the
Xensource CentOS 3.1,0 distribution for RHEL 4.

I have installed the xen from source not from the rpms.
All the hints will be greatly appreciated...
Thanking you,
Kashif
Use the RPM, and edit your own locally built grub.conf. Seriously.
