Hi all,
A new python based migration utility for migrating your xend virtual machines to XCP is now available at:
http://www.xen.org/products/cloud_projects.html
It can generate XVAs from your xend based HVM and paravirtualised virtual machines.
It can also steam your VM directly to a XenServer/XCP host over HTTP or HTTPS.
Please read the README for pointers and guidelines on how to prepare your VMs for migration to XCP. Most PV based virtual machines will need some preparation work.
Thanks to Stephen Spector and Dave Scott!
Enjoy,
David

If anyone has feature requests, direct them here.
The next feature i'll be working on is supporting kernels loaded from the
Dom0. The kernel images will have to be copied to the XenServer/XCP Dom0.

Hi David!
My Xen domU in my open source dom0 (Debian) have this configuration file:
----
bootloader = '/usr/bin/pygrub'
extra = 'console=hvc0'
memory = '64'
disk = [
'phy:/dev/HyperVG01/guest01-root,xvda1,w',
'phy:/dev/HyperVG01/guest01-swap,xvda2,w',
]
name = 'guest01'
vif = [ 'mac=00:01:64:4b:0d:2e, vifname=guest01-eth0, bridge=eth0' ]
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
----
My guest01 /etc/fstab file:
proc /proc proc defaults 0 0
/dev/xvda1 / ext3 relatime,errors=remount-ro 0 1
/dev/xvda2 none swap sw 0 0
BUT, this is for open source Xen domU, within the XenServer, the guest01
should be:
proc /proc proc defaults 0 0
/dev/xvda1 /boot ext2 defaults 0 2
/dev/mapper/vdwuaf1-root / ext3 errors=remount-ro 0 1
/dev/mapper/vdwuaf1-swap_1 none swap sw 0 0
And the partition table of the guest01:
guest01:~# fdisk -lu /dev/xvda
Disk /dev/xvda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders, total 16777216 sectors
Units = sectors of 1 * 512 = 512 bytes
Disk identifier: 0x0009c181
Device Boot Start End Blocks Id System
/dev/xvda1 * 63 498014 248976 83 Linux
/dev/xvda2 498015 16771859 8136922+ 8e Linux LVM
You tool can recreate the partition scheme? Or it just copy the domU as is?
I have many others domU like this to copy...
Thanks!
Thiago

I'm confused,
You supply 2 fstabs there, one using LVM, one without. Which one is it?

Exactly!
The first one is for my domU hosted at my open source Xen (powered by
Debian), the second fstab, is the new one, used for my guests hosted at my
XenServers.
Thanks!

If you change xvda1 to xvda, change xvda2 to xvdb it will work fine.
Change references in /boot/grub/menu.lst of xvda1 to xvda
Change references in /etc/fstab of xvda1 to xvda, and xvda2 to xvdb.
Understand?

Yeah! Sure!
Today I'm doing this work manually... I mean, to copy a VM from open source
Xen to the XenServer I do:
1- stop the VM on my debian dom0;
2- mount its root file system under /mnt/source;
3- export it via NFS;
4- At the XenServer, I boot the sysrescuecd (a live system);
5- fdisk the /dev/sda;
6- create the LVM volumes;
7- mount /dev/vg01/root under /mnt/target;
8- mount /dev/sda1 under /mnt/target/boot;
9- mount the debian dom0 nfs server under /mnt/source;
10- cp /mnt/source/* /mnt/target/
11- edit the /etc/fstab and the grub's menu;
12- shutdown the VM;
13- Convert it from HVM to PVM;
14- start the VM;
Thanks,
Thiago

So, your script can make a new partition scheme and a new fstab for my VMs
before stream it to the XenServer?
Because I have more than 100 VMs to copy! :-/

No im afraid not.
YOU have to make these changes to menu.lst and fstab before migration.
If your VMs are the exact same, this should be easily scripted. i.e.
vmdisk="/dev/xen/vm1root"
mount $vmdisk /mnt/tmp
sed -i.bak -e 's/xvda1/xvda/g' -e 's/xvda2/xvdb/g' /mnt/tmp/etc/fstab
/mnt/tmp/etc/fstab
umount /mnt/tmp

Hi David,
Could I migrate a Citrix XenServer VM to XCP as well?

You can, but you dont need this tool, just export the VM in XenServer to an
XVA and do a xe vm-import on XCP.

I had thought about this one.
If you have virtio drivers installed then its less likely.
If you don’t, then it should be possible, you’ll have to convert the image to a RAW image before running it through the tool.

No im afraid not.
YOU have to make these changes to menu.lst and fstab before migration.
If your VMs are the exact same, this should be easily scripted. i.e.
vmdisk="/dev/xen/vm1root"
mount $vmdisk /mnt/tmp
sed -i.bak -e 's/xvda1/xvda/g' -e 's/xvda2/xvdb/g' /mnt/tmp/etc/fstab /mnt/tmp/etc/fstab
umount /mnt/tmp

So, your script can make a new partition scheme and a new fstab for my VMs before stream it to the XenServer?
Because I have more than 100 VMs to copy! :-/

Wow, what a pain :)
2010/3/15 Martinx - ジェームズ <thiagocmartinsc@gmail.com<mailto:thiagocmartinsc@gmail.com>>
Yeah! Sure!
Today I'm doing this work manually... I mean, to copy a VM from open source Xen to the XenServer I do:
1- stop the VM on my debian dom0;
2- mount its root file system under /mnt/source;
3- export it via NFS;
4- At the XenServer, I boot the sysrescuecd (a live system);
5- fdisk the /dev/sda;
6- create the LVM volumes;
7- mount /dev/vg01/root under /mnt/target;
8- mount /dev/sda1 under /mnt/target/boot;
9- mount the debian dom0 nfs server under /mnt/source;
10- cp /mnt/source/* /mnt/target/
11- edit the /etc/fstab and the grub's menu;
12- shutdown the VM;
13- Convert it from HVM to PVM;
14- start the VM;
Thanks,

If you change xvda1 to xvda, change xvda2 to xvdb it will work fine.
Change references in /boot/grub/menu.lst of xvda1 to xvda
Change references in /etc/fstab of xvda1 to xvda, and xvda2 to xvdb.
Understand?
2010/3/15 Martinx - ジェームズ <thiagocmartinsc@gmail.com<mailto:thiagocmartinsc@gmail.com>>
Exactly!
The first one is for my domU hosted at my open source Xen (powered by Debian), the second fstab, is the new one, used for my guests hosted at my XenServers.
Thanks!

2010/3/15 Martinx - ジェームズ <thiagocmartinsc@gmail.com<mailto:thiagocmartinsc@gmail.com>>
Hi David!
My Xen domU in my open source dom0 (Debian) have this configuration file:
----
bootloader = '/usr/bin/pygrub'
extra = 'console=hvc0'
memory = '64'
disk = [
'phy:/dev/HyperVG01/guest01-root,xvda1,w',
'phy:/dev/HyperVG01/guest01-swap,xvda2,w',
]
name = 'guest01'
vif = [ 'mac=00:01:64:4b:0d:2e, vifname=guest01-eth0, bridge=eth0' ]
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
----
My guest01 /etc/fstab file:
proc /proc proc defaults 0 0
/dev/xvda1 / ext3 relatime,errors=remount-ro 0 1
/dev/xvda2 none swap sw 0 0
BUT, this is for open source Xen domU, within the XenServer, the guest01 should be:
proc /proc proc defaults 0 0
/dev/xvda1 /boot ext2 defaults 0 2
/dev/mapper/vdwuaf1-root / ext3 errors=remount-ro 0 1
/dev/mapper/vdwuaf1-swap_1 none swap sw 0 0
And the partition table of the guest01:
guest01:~# fdisk -lu /dev/xvda
Disk /dev/xvda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders, total 16777216 sectors
Units = sectors of 1 * 512 = 512 bytes
Disk identifier: 0x0009c181
Device Boot Start End Blocks Id System
/dev/xvda1 * 63 498014 248976 83 Linux
/dev/xvda2 498015 16771859 8136922+ 8e Linux LVM
You tool can recreate the partition scheme? Or it just copy the domU as is?
I have many others domU like this to copy...
Thanks!
Thiago
2010/3/15 David Markey <admin@dmarkey.com<mailto:admin@dmarkey.com>>
If anyone has feature requests, direct them here.
The next feature i'll be working on is supporting kernels loaded from the Dom0. The kernel images will have to be copied to the XenServer/XCP Dom0.

Hi all,
A new python based migration utility for migrating your xend virtual machines to XCP is now available at:
http://www.xen.org/products/cloud_projects.html
It can generate XVAs from your xend based HVM and paravirtualised virtual machines.
It can also steam your VM directly to a XenServer/XCP host over HTTP or HTTPS.
Please read the README for pointers and guidelines on how to prepare your VMs for migration to XCP. Most PV based virtual machines will need some preparation work.
Thanks to Stephen Spector and Dave Scott!
Enjoy,
David

Of course! In fact, you can migrate ANY Linux from <-> to whatever you want.
