Dear Pasi,

 

> How do you install the guest?

 

I copied the kernel and initial ramdisk image from the images/xen directory on the CentOS 4.7 x32 cd-rom and specified this kernel and initrd in my guest config in /etc/xen on Dom 0. Then I successfully finished the guest installation using HTTP method. I reached the end where I was asked to reboot after installation completes.

I did not use virt-manager at all. I used "xm create domain".

I have earlier provided logs from /var/log/xen/ and xm dmesg in this xen-devel mailing list topic.

 

> do you have selinux or apparmor? Did you disable them?

 

On RHEL/CentOS/Fedora systems I will normally disable SELinux by using the following commands:

 

# echo 0 > /selinux/enforce

 

# vi /etc/selinux/config

 

and change the policy to disabled.

 

I am not very sure about the SELinux implementation on OpenSUSE 11.1 and I forgot to check this. Later in the day I will use yast to check the SELinux and apparmor settings.

 

Thank you!!!

How do you install the guest?

or virt-manager?

What's the error you get?

Did you check "xm log" ? "xm dmesg" ?

/var/log/messages or /var/log/syslog on dom0?

do you have selinux or apparmor? Did you disable them?
