Fluent virt-install Windows XP HVM DomU at Solaris (SNV_92) Dom0



Due to known bug virt-install is not approved method for mentioned installation. However, simple bash script (monitor) provides an option to attach cdrom via xm block-attach command immediately when it will be lost by virt-install after first DomU reboot.
Start virt-install for Windows HVM DomU in first terminal session:-



virt-install -n WinXP --hvm -r 1024 --vnc \
-f /export/home/images/winxp.img -s 5 \
-c /export/home/isos/winxp.iso



At the same time start running following script in second terminal session:-



#!/bin/bash 
COUNTER=1
while [  $COUNTER -eq 1 ]; do
 COUNTER=`xm list -l WinXP|grep cdrom|wc -l`
 sleep 1
done
xm block-attach WinXP file:/export/home/isos/winxp.iso hdc:cdrom r
xm reboot WinXP



When scripts exists wait for several seconds.
and issue from same terminal:-



vncviewer localhost:0



to proceed with install as normal.
Message in first terminal session.



Guest installation complete... restarting guest.
libvir: Xen Daemon error : failed Xen syscall xenDaemonDomainDumpXMLByID failed to find this domain -13551186
exception was: virDomainGetXMLDesc() failed failed Xen syscall xenDaemonDomainDumpXMLByID failed to find this domain -13551186
Domain installation may not have been
successful.  If it was, you can restart your domain
by running 'virsh start WinXP'; otherwise, please
restart your installation.

Virt-install F9 DomU at Xen 3.2.1 F8 Dom0 (64-bit)



Install may be performed either by virt-install or by virt-manager.
View [1] for details. However, after F9 DomU run other DomUs may be managed
only from command line by "xm". Virt-manager cannot connect to daemon
xend until next Dom0 reboot. Running F8, CentOS 5.1, SNV90 DomUs doesn't
affect virt-manager functionality. I also have to notice that F9 DomU
may be managed only by "xm" from command line. Been started and shutdown
once via virt-manager it makes virt-manager unable to reconnect to xend.
To start already created F9 DomU:-
# xm start f9pvm
and from another terminal session
connect to F9 DomU:-
# vncviewer localhost:0

Install SNV91 DomU at SNV91 Dom0 on boards with integrated NIC RTL8110SC



ASUS boards P5K Premium/WIFI, P5K3 Deluxe, P5E3 Deluxe have as second
NIC integrated on the board RTL8110SC.
RTL8110SC (vs Marvell 88E8056 first NIC integrated on the board) is GLDv3 NIC and may be used for Solaris xVM PV and HVM DomUs creation at Solaris (Nevada) Dom0.
However, straight forward attempt to install SNV DomU in DHCP mode
will time out at DHCP request phase due to failure checksum offloading on Realtek 8110SC.
Core idea of network troubleshooting and modification of /etc/system
in SNV DomU were suggested by Jurgen Keil in the thread at xen-discuss
forum@opensolaris.org. Utility "tcpdump -s 1600 -vv" running on another host of the LAN (where SNV Dom0 is located) during SNV DomU DHCP request will register bad UDP checksums:-


08:38:01.361741 arp who-has 192.168.1.1 tell 192.168.1.39
08:38:02.220179 IP (tos 0x0, ttl 255, id 19410, offset 0, flags [DF], proto: UDP (17), length: 328) 0.0.0.0.bootpc > 255.255.255.255.bootps: [bad udp cksum 19ae!] BOOTP/DHCP, Request from 00:16:3e:29:b2:18 (oui Unknown), length: 300, xid:0x872bd9e3, secs:124, flags: [none] (0x0000)

Due to DHCP request is a broadcast request same thing happens
on DSL Modem, acting as a DHCP bridge for the LAN.
DSL Modem just discards every DHCP request sent by xnf0 (DomU)
via rge0 interface (Dom0). Switching rge0 to rtls0 fixes
problem immediately. Box has a third NIC RTL8139 plugged into
PCI slot.
Procedure following bellow is a workaround for mentioned issue for Solaris rge0 Ethernet interface.
1. Install DomU with static IP address
2. After reboot modify /etc/system and add the line :
set xnf:xnf_cksum_offload = 0
3. Run sys-unconfig


This program will unconfigure your system. It will cause it
to revert to a "blank" system - it will not have a name or know
about other systems or networks.
This program will also halt the system.
Do you want to continue (y/n) ? y
Then the system will shutdown and when you reboot,
it asks all new server questions out of the box:
What your server name is ?
Are you on the network ?
Ask for DHCP or IP ?
What is your netmask ?
Do you have a defaultrouter ?
Root passwd?
Finally it run the kdmconfig and tries to configure
your X-display adapter and monitor size,mouse ps/2 USB or serial


4. During boot up specify request IP address via DHCP
and this time DHCP request won't be timed out.
Created SNV DomU may communicate with internet
with no problems.

Fedora 8 (64-bit) as a flexible target for Xen 3.2.1 Dom0 install



Procedure described bellow installs packages mercurial, dev86, python-virtinst,virt-manager,virt-viewer. Virt-install,virt-manager as well as pygrub and hvmloader appear to be completely functional on Xen 3.2.1 F8 Dom0 and allow to create PV and HVM guests like on enterprise class systems.
Commands xm start/stop/shutdown/reboot DomainName provide
ability to manage created domains as on native Xen 3.1 F8 Dom0.

# cd /usr/src/
# hg clone http://xenbits.xensource.com/xen-3.2-testing.hg
# cd xen-3.2-testing.hg
# make world vmxassist=n
# make install
  
Determine the name of the Xen Linux kernel version that was installed.

# ls /lib/modules

There should be a directory for the Xen Linux kernel (e.g., 2.6.18.8-xen)
Generate the module dependency list and map files

# /sbin/depmod 2.6.18.8-xen

To create the Xen initial ramdisk image remove from 
/etc/modprobe.conf pata_jmicron entry and run:-

# /sbin/mkinitrd /boot/initrd-2.6.18.8-xen.img   2.6.18.8-xen 

Disable tls
 
# mv /lib64/tls /lib64/tls.disabled

Set xend service to start

# /sbin/chkconfig --add xend
# /sbin/chkconfig xend on

Edit /usr/bin/pygrub and replace:-
sys.path = [ '/usr/lib/python' ] + sys.path
with
sys.path = [ '/usr/lib64/python' ] + sys.path

Modify xend-config.sxp:-
Set "xend-unix-server"  to "yes"


Edit /boot/grub/grub.conf and copy one of the existing boot 
entries to make the required changes for Xen and reboot into new kernel.

Virt-install at Xen 3.2.1 F8 Dom0 (64-bit)



Package python-virtinst may be safely installed on Xen 3.2.1 F8 Dom0.
Minor tuning of /usr/bin/pygrub and xend-config.sxp makes possible
creating Linux DomUs with virt-install utilizing loop mounted ISOs



# mkdir -p /mnt01/tmp
# mount -o loop,ro CentOS51.iso  /mnt01/tmp



and /mnt01/tmp as NFS shares for parameter
--location nfs:IP-ADDRESS-Dom0:/mnt01/tmp
in virt-install command line or interactively


1.Install F8 xen disabled
2.Install Xen 3.2.1 from source on F8 instance ([3]).
