The ethernet network bridge on OpenSUSE 11.1 is eth0.

(F10 with Xen 3.3.1 src.rpm been installed along with generated packages) with libvirtd & dnsmasq up and running you can specify
 vif=['bridge=virbr0' ] to detect DHCP Server at your Dom0.

View for instance :-
http://bderzhavets.wordpress.com/2009/05/07/backport-zfs-support-to-xen-331-f10-dom0-kernel-2630-rc3-tip/

I don't have any experience with OpenSuse 11.1 . I hardly remind they tried 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 your OpenSuse 11.1 Dom0 is on "dhcp" bridge itself , then no problems. Just vif=['bridge=eth0'].

Dear Boris,

This means I have to install a DHCP server or dnsmasq in my Dom 0, listening on my Dom 0's IP address, so that it can assign dynamic IP addresses to the DomU.

By the way, are there any paravirtualized device drivers that I can install in DomU to improve the performance of the virtual machine?

Thank you.

Login as jack/jack to text console.

Wait until :-

$ pfexec ifconfig -a

will show up your IPv4 address

$ mkdir .vnc
$ cp .Xclients .vnc/xstartup
$ vncserver

Connect via vncviewer IP-DomU:1 from another terminal session to OSOL DomU. In case OSOL installer will fail to obtain IP via DHCPDISCOVER,
let me know. It might happen and requires Solaris Kernel Model Debugger
to disable checksum offloading at boot up. Seems to be hardware dependent issue for OSOL 2009.06

Dear All,

I am trying to install OpenSolaris 2009.06 32-bit paravirtualized guest on OpenSUSE 11.1 32-bit paravirt-ops enabled Xen 3.4.1-rc8 Dom 0 Kernel 2.6.30-rc6.

However, I am getting an opensolaris console login prompt. There is no GNOME DE for me to launch the GUI installer for OpenSolaris. I am using the OpenSolaris LiveCD 32-bit.

I noticed under the guest domain configuration there is a parameter called 'extra' kernel parameter. Does the 'nowin' argument stand for no graphical windows?

http://2.bp.blogspot.com/_zzjv8MCM2sk/SmoT5uzjF6I/AAAAAAAAAFU/2Y3KNWPUwWk/s1600-h/05.jpeg

Then I also get the "invalid disk device number (768)" error. Do I need to use xvda instead of hda?

Thank you very much.

Dear Boris,
 
My next step will be a 64-bit Xen Dom 0 host.

Teo, it is up to you how to manage, if you just having fun.
Otherwise, downloading 64-bit OpenSuse 11.1 ISO image
takes just 12-14 hr even at slow ADSL speed ( like 100 KB/sec).
Install takes 30 minutes and brings you to the trusted results, instead
of wasting a lot of time in case of business environment assignment.
Pasi has 32-bit experience due to hardware limitations, which you don't
have.

Boris.

Dear Boris,
 
My colleague installed OpenSUSE 11.1 32-bit on the Core 2 Duo machine in our labs. Please see my earlier replies in the same topic.
 
I was too lazy to reformat and install 64-bit OpenSUSE, so I proceeded with Xen Dom 0 pvops kernel compilation on 32-bit Linux host.
 
I admit I am getting a lot of headache. Haha.

Once again, i don't see any reason to to run 32-bit OS on Core2Duo,
unless you like Xen head ache. Core development (PVOPS) is obviously
running in 64-bit environment.

Why it wouldn't ? If your image stays  the same.

That is not supposed to happen. I would suggest clean OS (without any built in xen presence) install , followed by  Xen 3.4.1+pvops kernel clean install.

Boris.

Dear All,
 
I am very puzzled. In investigating the cause of the sudden success of the CentOS 4.7 32-bit PV guest being able to run, I have uninstalled virt-manager and all of its dependencies:
 
docbook
python-gtk-vnc
xen-libs 3.3.1
scrollkeeper
xen-tools 3.3.1
libvirt 0.4.6
libvirt-python
vm-install 0.3.24
 
Then I proceeded to "make uninstall" in xen-3.4-testing source tree, which also removed my self compiled Xen Dom 0 pvops enabled kernel, initrd and kernel modules.
 
After doing the above, I re-installed back the Xen hypervisor, libraries and tools, and also the kernel, initrd, and modules. Then I proceeded to reboot my machine. After rebooting, my CentOS 4.7 32-bit PV guest is still able to start and run!
 
I am still very puzzled! What causes the PV guest initially cannot start? Then what subsequently causes the PV guest to suddenly be able to start and run???
 
***scratches head***
 
Anyway my CentOS 4.7 guest domain is now running. I shall now proceed to virtualize OpenSolaris 2009.06.
 
Thank you.

Hi Pasi,
 
It's very strange. Suddenly my CentOS 4.7 32-bit PV guest is able to start!!! Previously it refuses to start at all.
 
I think I must have changed something in Dom 0 when I attempted "yast --install virt-manager". This action might have solved the problem. When I tried to install virt-manager, it also tries to install xen-libs-3.3.1 and xen-tools-3.3.1 as dependencies. However, I started off my Xen Dom 0 pvops kernel install with Xen 3.4.1 rc8 branch.
 
I need to investigate more why suddenly my CentOS 4.7 32-bit PV guest is able to start.

Hi Pasi,
 
I realized that Fedora 10 32-bit anaconda installer does not install PAE kernel after mounting the guest disk image file. I mounted the guest disk image file using losetup and kpartx which adds device nodes to /dev/mapper. I examined the /boot directory after mounting the guest disk image file and found no PAE vmlinuz and initrd.
 
Still using the mounted Fedora 10 32-bit guest disk image file, I changed root to the guest disk filesystems and attempted to install the PAE kernel. Then I modified menu.lst to boot the PAE kernel. After modifying the grub configuration of the guest domain, I un-mounted the guest filesystem.
 
I proceeded to boot the F10 32-bit guest, since I changed to PAE kernel. It is able to boot now (since the PAE kernel is xen-aware) but then it complains cannot mount /dev/root. Probably something to do with the PAE initrd file.

Fedora 10 installer has a bug, as a default it installs non-PAE kernel for
xen domU. You need to use a kickstart script (like this) to fix it:
http://pasik.reaktio.net/fedora/f10-xen-domu-ks.cfg

The important lines being:

-kernel
kernel-PAE

(Fedora 10 and Fedora 11 default kernels are compiled with pv_ops Xen domU
support enabled, so there's no need for separate kernel-xen with these distros).

Fedora 11 doesn't have that installer bug, so it installs right
out-of-the-box as Xen domU.

What's the error you get when you start the guest after installation?
Please paste the "xm log" as text.

I don't have any problems with CentOS 5.3 dom0.
