Re: [Xen-devel] Unable to Configure Xen Dom 0 in Jeremy's PVOPS Kernel

Dear Boris,
Based on your given information, I have managed to configure static IP
address inside OpenSolaris UNIX PV guest.
These are the two crucial lines:
echo 192.168.1.45 netmask 255.255.255.0 mtu 1492 >
/etc/hostname.xnf0
echo 192.168.1.102 > /etc/defaultrouter
Please see screenshot here:
http://3.bp.blogspot.com/_zzjv8MCM2sk/Sm21uPKvVXI/AAAAAAAAAKU/NDQqKSld5v4/s1600-h/03.jpeg
May I know whether there are any PV device drivers for me to install to
improve PV guests' performance? What are the recommended benchmark tools to
measure I/O performance of PV guests?
Thank you!!!

Dear Boris,
I have to use static IP instead of dhcp because we are going to run
servers.
I have managed to enable GNOME GUI and solved the DNS resolver issue
based on the following guides:

http://defect.opensolaris.org/bz/show_bug.cgi?id=125
Please see my screenshots here:

I shall now work on hard coding static IP.

1) I need to edit ~/.vnc/xstartup so that it will launch a GUI
interface instead of a text console. During installation, I was able to copy
.Xclients to xstartup but after installation, .Xclients do not exist anymore

was able to port the GNOME desktop to my remote vnc client.

pfexec ifconfig xnf0 down

pfexec ifconfig xnf0 up
pfexec route add default 192.168.1.45

Dear All,
I am now able to run OpenSolaris 2009.06 32-bit
paravirtualized on Xen 3.4.1-rc8 Dom 0 Kernel 2.6.30-rc6 on OpenSUSE 11.1
32-bit.
However, there are still some outstanding configuration
issues as I am not very familiar with Solaris UNIX. I am more of a Linux
guy.
1) I need to edit ~/.vnc/xstartup so that it will launch a
GUI interface instead of a text console. During installation, I was able to
copy .Xclients to xstartup but after installation, .Xclients do not exist
anymore under my personal account. I have configured vncserver before in
Linux and I was able to port the GNOME desktop to my remote vnc client.
2) I could not hard code IP address (static definition, not
dhcp) and network settings inside OpenSolaris like what I usually do in
Linux. It seems that configuring /etc/hostname.xnf0 did not help. My VM's
actual hostname is "opensolaris", so do I change that to
/etc/opensolaris.xnf0? After OpenSolaris PV guest boots up, I had to
manually configure the IP address, netmask and default route.
3) Configuring name servers in /etc/resolv.conf inside
Solaris did not work. But I could still go out to the internet by pinging
the IP addresses of Singapore's Starhub and Singnet ISP DNS servers. Just
that name resolution didn't work on Solaris.
Please see the screenshots here:
http://teo-en-ming-aka-zhang-enming.blogspot.com/2009/07/creating-opensolaris-unix-200906-32-bit.html
More questions:
4) Are there any paravirtualized device drivers/tools I can
install inside PV guests to enhance VM's performance? Like VMware tools?
5) Are there any benchmarking tools to measure I/O
throughput of my PV guests?
Thank you very much.

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.

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

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

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.

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.

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.
