Ubuntu Hardy HVM vs PV DomU at opensolaris 2008.11 Dom0

Start with install HVM on zvol (/dev/zvol/dsk/bigpool/disk3)








When done:-

# apt-get install build-essentials
# apt-get install linux-image-xen

Download ethtool-6 package and install it with intend to disable checksums offloading
on PV DomU with image on same zvol.

Add to /etc/rc.local :-

to disable checksum offloading at DomU (due to "rge" Solaris Driver at Dom0) and reboot.
Set up VNC at Ubuntu Hardy PV DOMU per [1]:-











Notice that install Ubuntu HVM and runtime performance at opensolaris 2008.11 Dom0
is extremely low versus same HVM perfomance at Xen 3.3.1 openSUSE 11.1 Dom0 on
the same box with C2D E8400 and 8 GB RAM.
Actually, Linux as well as Nevada HVM DomUs demonstrate very low performance even
been installed on zvols. Paravirtual DomUs behave at opensolaris 2008.11 absolutely
normal been installed on zvol's images.

xVM on opensolaris 2008.11

My primary target was testing xVM performance at opensolaris 2008.11(based on 101b Nevada build). Solaris Nevada works smoothly with images located on UFS and zvols.Opensolaris 2008.11 requires only zvols as image devices for Xen Guests to be installed in reasonable time.I believe it's a known issue caused by ZFS. From my standpoint the most impressive UI feature is Package Manager. It's really helpful.


Install all members of Virtualization group via Package manager.

Creating zpool :-


# zpool create xvmpool c4t0d0p2 (3)
# zfs create -V 25G xvmpool/snv-disk

Log out root and run:-

$ pfexec virt-manager

Set installation partition to /dev/zvol/dsk/xvmpool/snv-disk
Attempt to use image file like /export/home/images/root.img , located on ZFS will make virt-manager
(virt-install) performance unacceptable, at least through my experience.











CentOS 5.2 PV guest snapshots:-








SNV_103 HVM been built with /dev/zvol/dsk/rpool/disk1 (zfs create -V 12G rpool/disk1)

1.Getting xVM to work in Opensolaris 2008.05

Install SNV103 PV DomU with ZFS image at Xen 3.3.1. openSUSE 11.1 Dom0 (all 64-bit)

During installation phase we would have to drop to shell and undertake some special actions to prepare runtime profile.Pygrub won't be able to load DomU utilizing ZFS based image. In particular, ZFS-ID of boot environment will be ontained to compose extra line in runtime profile.


Start install as usual via profile :-

name = 'Solaris103PV'
memory = '2048'
disk = [ 'file:/home/boris/snv103.iso,6:cdrom,r','phy:/dev/sdb12,0,w']
vif = [ 'bridge = br1' ]
bootloader = '/usr/bin/pygrub'
kernel = '/boot/platform/i86xpv/kernel/amd64/unix'
ramdisk = '/boot/amd64/x86.miniroot'
extra = '/platform/i86xpv/kernel/amd64/unix - nowin -B install_media=cdrom'

Select ZFS on image device and request manual reboot. At the end of package deployment phase drop to shell at DomU and run

# bootadm update-archive -R /a

Copy kernel and boot_archive off the image to Dom0

# /a/usr/bin/scp -S /a/usr/bin/ssh \
/a/platform/i86xpv/kernel/amd64/unix \
192.168.1.33:/etc/xen/nevada
# /a/usr/bin/scp -S /a/usr/bin/ssh \
/a/platform/i86pc/amd64/boot_archive \
192.168.1.33:/etc/xen/nevada

Get the ZFS-ID of the /ROOT/snv_103 zpool. First, find out the pool_guid.
Follow [1]:-

# zpool get guid rpool

1.Installing Opensolaris 2008.11 RC2 on a Linux (RedHat/Centos) dom0

Install Ubuntu Hardy PV DomU & VNC at Ubuntu Hardy Dom0 (all 64-bit)

This posting deals with utilizing same image device for loading HVM and PV
Ubuntu Hardy DomUs at Ubuntu Hardy Dom0 (2.6.24-21-xen #1 SMP Mon Aug 25 18:56:44 UTC 2008 x86_64 GNU/Linux). This approach allows to avoid traditional "debootstrap" procedure as well as taking a long time "apt-get install ubuntu_desktop", what is, actually, 400 MB download. It also provides a workaround to get Gnome Desktop working stable at Ubuntu PV DomU no matter on Xen Release (>=3.1.2) and OS (Solaris,Linux) running at Dom0.
Install Ubuntu Hardy HVM DomU via hvm-profile:-

root@boris-desktop:/etc/xen/vm# cat u8.cfg
kernel = "/usr/lib/xen/boot/hvmloader"
builder = 'hvm'
memory = 2048
name = "U8HVM"
vcpus = 1
vif = [ 'type=ioemu, bridge=eth0' ]
disk = [ 'phy:/dev/sda9,hda,w!','phy:/dev/loop0,hdc:cdrom,r' ]
device_model = '/usr/lib/xen/bin/qemu-dm'
vnc=1
boot='d'
  

**********************************
Ligin to HVM DomU and run :-
**********************************

# apt-get install linux-image-xen
# apt-get install vim
********************************************

When connect via vncviewer from Dom0, getting Error Window “Gnome Setting Daemon failed to start”. To fix Gnome Setting Daemon failures to start, open vnc session with DomU ([2]) and run in gnome terminal ([3]):-
$ gconf-editor
and disable mouse and keyboard plugins.
Relogin to Ubuntu PV DomU via vncviewer.
Gnome Desktop should be working fine.

PV-Grub on OpenSuse 11 PV DomU at Xen 3.3 CentOS Dom0 (all 64-bit)

We use the most recent Xen 3.3 port to CentOS 5.2 via http://www.gitco.de/repo/xen3.3.0.
Regarding Xen 3.3 Feature: PV-GRUB in general, please, view
blog.xen.org


Prepare grub's /boot/grub/menu.lst at DomU side for pv-grub booting.
Actually, we need just one entry into menu.lst and it has
to be created mannualy:-

SUSE11PV:~ # cat /boot/grub/menu.lst

Pygrub & loading OpenSuse 11 PV DomUs at Xen 3.3 CentOS 5.2 Dom0 (all 64-bit)

Due to known issue attempt to virt-install OpenSuse 11 PV DomU at Xen 3.3 CentOS 5.2 Dom0
from nfs share fails immediately at startup. Approved procedure via Internet repositories for OpenSuse 10.3 requires internet connection speed at least 700 Kbit/sec to take reasonable time. OpenSuse 11.1 (with pygrub implemented) is due only in December 2008.
However, pygrub coming along with current Xen Release 3.3(3.2.1) does allow to load
OpenSuse 11 DomUs at CentOS 5.2 (RHEL 5.2) Dom0 with no problems. I have not made any
testing for native Xen 3.1 pygrub coming with CentOS 5.X, but there is a good chance,
that it would work as well. Schema shortly described bellow would never work vice versa unless OpenSuse 11.1 would have pygrub issue fixed.
Per release notes for OpenSuse 11.1 looks like RH PV Guests are supposed to run
at OpenSuse 11.1 via pygrub, e.g. vm-install for this quests would work via NFS shares, not only via Internet Repositories like it works at mean time

Actually any image transfered via "scp" to CentOS 5.2 Dom0 may be easily converted
to LVM for performance improvement. In case when Suse DomU is utilizing LVM for
root image two "dd" conversions might be required to transfer DomU to remote
Xen 3.3 CentOS 5.2 Dom0.

FireFox 3.0.1 & Java Web Start on 64-bit Xen 3.3 CentOS 5.2 Dom0

This posting follows up the recent one Vncserver on SNV97 DomU at Xen 3.3 CentOS 5.2 Dom0 (64-bit) and is targeting enabling Sun's Java Web Start in FireFox 3.0.1 Web Browser with 32-bit JRE 6.0 plugin installed on 64-bit Linux.
First of all install 32-bit Sun JRE 6.0 for Linux by running
./jre-6u<version>-linux-i586-rpm.bin.
Then install FireFox 3.0.1 (32-bit) into folder /usr/tmp/firefox for instance
Create following symlink to make firefox aware of JRE :-

[root@ServerRHL52]# cd /usr/tmp/firefox/plugins
[root@ServerRHL52 plugins]# ln -s /usr/java/jre1.6.0_07/plugin/i386/ns7/libjavaplugin_oji.so \
> libjavaplugin_oji.so
  

Sun's test:-

Consider two samples for verification.


1. Vncserver started on SNV97 DomU allocates two ports 580(X) and 590(X),where (X) is available display number.Port 580(X) may be used for http://IP-DomU:580(X) connection to DomU , port 590(X) may be used by vncviewer IP-DomU:(X) connection.Both ways initiate loading Java Applets from DomU into Dom0.Snapshots bellow demonstrates loading VncViewer Applet via launching Firefox 3.0.1 browser to http://IP-DomU:5801.

2. Another demonstration of Java Web Start availability is running Sun Download Manager
(SDM) in browser FireFox 3.0.1.

Vncserver on SNV97 DomU at Xen 3.3 CentOS 5.2 Dom0 (64-bit)

Sun Xvnc implementation for Nevada, committed in build 76 provides 3 options. Third one is to start vncserver by hands. It allocates two ports 580(X) and 590(X),where (X) is available display number.Port 580(X) may be used for http://IP-DomU:580(X) connection to DomU , port 590(X) may be used by vncviewer IP-DomU:(X) connection.Both ways initiate loading Java Applets from DomU into Dom0. Connection via vncviewer has been selected on CentOS 5.2 Dom0 (with Sun JDK 6.0 installed) due to issue with Java Web Start and FireFox on 64-bit Linux. By some reasons first and second options provided by official Sun Xvnc failed on SNV97 DomU, successfully installed via pygrub in text mode as usual.Following bellow is a snapshot of DomU start up.
