This means that OSOL installer (by default ) = will issue DHCPDISCOVER via your Xen bridge, looking for DHCP server on you= r LAN. Only on RHEL 5.3
(F10 with Xen 3.3.1 src.rpm been installed along= with generated packages) with libvirtd & dnsmasq up and running you ca= n specify
 vif=3D['bridge=3Dvirbr0' ] to detect DHCP Server at you= r Dom0.

View for instance :-
http://bderzhavets.wordpress.com/20= 09/05/07/backport-zfs-support-to-xen-331-f10-dom0-kernel-2630-rc3-tip/
<= br>I don't have any experience with OpenSuse 11.1 . I hardly remind they tr= ied to reproduce RH's technology. Most probably they did it in SLES 11 (not= sure). Check for libvirtd&dnsmasq daemons up and running.
But if yo= ur OpenSuse 11.1 Dom0 is on "dhcp" bridge itself , then no problems. Just v= if=3D['bridge=3Deth0'].

Hi Pasi, =0A

I realized that=0AFedora = 10=0A32-bit anaconda installer does not install PAE kernel after mounting= =0Athe guest disk image file. I mounted the guest disk image file using=0Al= osetup and kpartx which adds device nodes to /dev/mapper. I examined=0Athe = /boot directory after mounting the guest disk image file and found=0Ano PAE= vmlinuz and initrd.

St= ill using the=0Amounted Fedora=0A10 32-bit guest disk image file, I changed= root to the guest disk=0Afilesystems and attempted to install the PAE kern= el. Then I modified=0Amenu.lst to boot the PAE kernel. After modifying the = grub configuration=0Aof the guest domain, I un-mounted the guest filesystem= .

= =0A
I proceeded to boot= =0Athe F10=0A32-bit guest, since I changed to PAE kernel. It is able to boo= t now=0A(since the PAE kernel is xen-aware) but then it complains cannot mo= unt=0A/dev/root. Probably something to do with the PAE initrd file.
