[Xen-users] XCP/XenServer Migration utility now available at xen.org
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 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

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. 2010/3/12 Martinx - ジェА璽爛 <thiagocmartinsc@gmail.com>> Really COOL!!!

Re: [Xen-devel] Re: [Xen-users] XCP/XenServer Migration utility now available at xen.org
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

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.

Re: [Xen-devel] Re: [Xen-users] XCP/XenServer Migration utility now available at xen.org
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 2010/3/15 David Markey <admin@dmarkey.com>> 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А璽爛 <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! >> Thiago >> >> 2010/3/15 David Markey <admin@dmarkey.com> >> >>> I''m confused, >>> >>> You supply 2 fstabs there, one using LVM, one without.

So, your script can make a new partition scheme and a new fstab for my VMs before stream it to the XenServer?

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 2010/3/15 Martinx - ジェА璽爛 <thiagocmartinsc@gmail.com>> 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! :-/ > > > 2010/3/15 David Markey <admin@dmarkey.com> > >> Wow, what a pain :) >> >> >> >> 2010/3/15 Martinx - ジェА璽爛 <thiagocmartinsc@gmail.com> >> >>> Yeah!

RE: [Xen-devel] Re: [Xen-users] XCP/XenServer Migration utility now available at xen.org
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! :-/

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

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!

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

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

Re: [Xen-devel] Re: [Xen-users] XCP/XenServer Migration utility now available at xen.org
Well, The partition scheme in your VM is the same before and after the migration. I think any different behaviour is outside the scope of this tool I think.
