Re: [Xen-devel] Unable to Configure Xen Dom 0 in Jeremy's PVOPS Kernel
Can you run
# tcpdump -s 1600 -vv >log & at Dom0
and check for wrong udp checksums at the time of issueing DHCPDISCOVER by OSOL installer. When Dom0 send to DomU DHCPOFFER, i would run same command at DomU.
Finally, i would capture tcpdump logs at Dom0 and at DomU when you fail
to obtain IP address for OSOL DomU, what causes udp packages to get discarded at corresponding ethetnet interface.
It looks for me as failure of checksums offloading.
Boris.

Dear Boris,
I used the same ethernet network bridge in both installation and
actually running of the pv guest. During installation, dhcpdiscover was sent
out by the opensolaris pv guest. Dom 0 also sent out DHCPOFFER. However,
opensolaris pv guest could not configure the virtual network interface using
dhcp. So I had to manually configure the virtual network interface.

OK. What happens if you put the same vif=['bridge=...'] in OSOL
installation
profile. Are you unable to get IP for install in this case ?

Dear Boris,
My CentOS 4.7 32-bit PV guest is getting the dynamic IP
address assignment from the dnsmasq dhcp server I have setup and configured
on Xen Dom 0 OpenSUSE 11.1 32-bit host correctly.
So I think the issue is OpenSolaris specific.

But if your OpenSuse 11.1

vif=['bridge=eth0'].

This means I have to

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.

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.

I was too lazy to reformat and install 64-bit

Once again, i don't see any reason to to run

That is not supposed to happen. I would suggest clean OS (without any

clean install.

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:
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???
Anyway my CentOS 4.7 guest
domain is now running. I shall now proceed to virtualize OpenSolaris
2009.06.

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.

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.
