Comments on Paravirtualization With Xen 4.0 On Debian Squeeze (AMD64)

Great HowTo, Falko!

Worked fine for me!! Do you have an HowTo for the above configuration in order to install Windows as HVM?

When using the xm create command i've had this error: Error: 'NoneType' object has no attribute 'rfind'

 using apt-get install xen-qemu-dm-4.0 solved this issue

root@ziomario:/home/mario# xm create /etc/xen/xen1.example.com.cfg

Using config file "/etc/xen/xen1.example.com.cfg".

Error: (1, 'Internal error', 'panic: xc_dom_boot.c:79: launch_vm: SETVCPUCONTEXT failed (rc=-1)')

 root@ziomario:/home/mario# nano /etc/xen/xen1.example.com.cfg

#bootloader = '/usr/lib/xen-default/bin/pygrub'
##  Disk device(s).#root        = '/dev/sda2 ro'disk        = [                  'file:/home/xen/domains/xen1.example.com/disk.img,sda2,w',                  'file:/home/xen/domains/xen1.example.com/swap.img,sda1,w',              ]##  Physical volumes#

#  Hostname

name        = 'xen1.example.com'

#  Networking

vif         = [ 'ip=192.168.0.101,mac=00' ]

#  Behaviour

on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'

I do think that network-bridge and vif-bridge (actually all network-* and vif-*) are not supported by Debian Xen. You are supposed to set up the network in /etc/network/interfaces as usuall.

HI

 is this possible to install lucid or hardy

 through PV. As you use maveric.

 Best Regards

Hi Falko

I followed your instruction on: https://www.howtoforge.com/paravirtualization-with-xen-4.0-on-debian-squeeze-amd64. I set up the guest as image. At the point to start the VM wit <font="Courier New">xm console</font> the VM boots up but hangs on: 

<code>Gave up waiting for root device.  Common problems:

 - Boot args (cat /proc/cmdline)

   - Check rootdelay= (did the system wait long enough?)

   - Check root= (did the system wait for the right device?)

 - Missing modules (cat /proc/modules; ls /dev)

ALERT!  /dev/xvda2 does not exist.  Dropping to a shell!

</code>

Here ist the content of the <font="Courier New">xen1.hostname.local.cfg</font>:

<code>kernel      = '/boot/vmlinuz-2.6.32-5-xen-amd64'

ramdisk     = '/boot/initrd.img-2.6.32-5-xen-amd64'

vcpus       = '1'

memory      = '1024'

root        = '/dev/xvda2 ro'

disk        = [ 'file:/usr/local/xen/domains/lweb.eas-4.name/disk.img,xvda2,w', 'file:/usr/local/xen/domains/lweb.eas-4.name/swap.img,xvda1,w', ]

name        = 'xen1.hostname.local'

vif         = [ 'ip=192.168.0.1,mac=01:12:4E:DD:EE:86' ]

on_poweroff = 'destroy'

on_reboot   = 'restart'

on_crash    = 'restart'</code>

Any suggestions how to solve my problem. I browsed the web, but I did not find any solutions.

Thank you for your help.

Kind regards, Laszlo

IN /etc/xen-tools/xen-tools.conf

I followed all the steps n successfully created vm.

At the end while asking about :

Creating Xen configuration file
Done
Setting up root password
Enter new UNIX password:

Retype new UNIX password:

passwd: Authentication token manipulation error

passwd: password unchanged

All done

i made a mistake over there my passwrd mismatch.

so when i start vm its asking about username and password.

so how i can log in to system? which  username and password i should provide?

 thx

xen-create-image --hostname=xen1.example.com --size=4Gb --swap=256Mb --ip=192.168.0.101 --memory=256Mb --arch=amd64 --role=udev --scsi --dist maverick --mirror=http://archive.ubuntu.com/ubuntu

this will install maverick but how can i install other distos like natty or oneiric? 

and is there any way to define path of iso stored on my hard drive to install OS?

Ganeti is a tool developped by google providing Xen with HA features like failover, live vm migration, secondary instance, ... Ganeti is quite tricky to install because of the amount of configuration needed to transform a standard debian squeeze to a ganeto node. The sitehttp://www.xenclustering.com provides some guidelines and a script for automated ganeti node initialization.
