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

I'm confused,

You supply 2 fstabs there, one using LVM, one without. Which one is it?

Hi David!

ÂMy Xen domU in my open source dom0 (Debian) have this configuration file:

----
bootloader = '/usr/bin/pygrub'
extraÂÂÂÂÂÂ = 'console=hvc0'
memoryÂÂÂÂÂ = '64'
diskÂÂÂÂÂÂÂ = [
ÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂ 'phy:/dev/HyperVG01/guest01-root,xvda1,w',
ÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂÂ 'phy:/dev/HyperVG01/guest01-swap,xvda2,w',
ÂÂÂÂÂÂÂÂÂÂÂÂÂ ]
nameÂÂÂÂÂÂÂ = 'guest01'
vifÂÂÂÂÂÂÂÂ = [ 'mac=00:01:64:4b:0d:2e, vifname=guest01-eth0, bridge=eth0' ]
>on_rebootÂÂ = 'restart'
on_crashÂÂÂ = 'restart'
----

ÂMy guest01 /etc/fstab file:

procÂÂÂÂÂÂÂÂÂÂÂ /procÂÂÂÂÂÂÂÂÂÂ procÂÂÂ defaultsÂÂÂÂÂÂÂ 0ÂÂÂÂÂÂ 0
/dev/xvda1ÂÂÂÂÂ /ÂÂÂÂÂÂÂÂÂÂÂÂÂÂ ext3ÂÂÂ relatime,errors=remount-ro 0ÂÂÂÂÂÂ 1
/dev/xvda2ÂÂÂÂÂ noneÂÂÂÂÂÂÂÂÂÂÂ swapÂÂÂ swÂÂÂÂÂÂÂÂÂÂÂÂÂ 0ÂÂÂÂÂÂ 0

ÂBUT, this is for open source Xen domU, within the XenServer, the guest01 should be:

procÂÂÂÂÂÂÂÂÂÂÂ /procÂÂÂÂÂÂÂÂÂÂ procÂÂÂ defaultsÂÂÂÂÂÂÂ 0ÂÂÂÂÂÂ 0
/dev/xvda1ÂÂÂÂÂ /bootÂÂÂÂÂÂÂÂÂÂ ext2ÂÂÂ defaultsÂÂÂÂÂÂÂ 0ÂÂÂÂÂÂ 2
/dev/mapper/vdwuaf1-root /ÂÂÂÂÂÂÂÂÂÂÂÂÂÂ ext3ÂÂÂ errors=remount-ro 0ÂÂÂÂÂÂ 1
/dev/mapper/vdwuaf1-swap_1 noneÂÂÂÂÂÂÂÂÂÂÂ swapÂÂÂ swÂÂÂÂÂÂÂÂÂÂÂÂÂ 0ÂÂÂÂÂÂ 0

ÂAnd 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/xvda1ÂÂ *ÂÂÂÂÂÂÂÂÂ 63ÂÂÂÂÂ 498014ÂÂÂÂÂ 248976ÂÂ 83Â Linux
/dev/xvda2 498015 16771859 8136922+ 8e Linux LVM

ÂYou tool can recreate the partition scheme? Or it just copy the domU as is?
ÂI have many others domU like this to copy...

Thanks!
Thiago

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.

Really COOL!!! I'm doing all this work manually until now!

Hi all,

A new python based migration utility for migrating your xend virtual machines to XCP Âis 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
