Re: [Xen-users] Manual p2v

[Paras pradhan <pradhanparas@xxxxxxxxx>]

Hi Jeff,

Thanks for the reply. What I did is:

* dd a image file and mounted as a loop file.

* copied everything including /boot except /proc /sys 

I will be using Paravirt and Pygrub. So I am a bit confused how to handle /boot using pygrub.

Thanks

Paras.

Hi Paras,

 

I've done p2v migrations another way, that we've found a little easier to manage:

 

-      stop all services but networking on the host to migrate (httpd, mysql, etc.)

-      create a target volume on our virtualization SAN with the desired size

-      mke2fs the target volume, and mount it somewhere

-      "rsync –a" the entire filesystem from the host we are migrating to the target volume (probably easier if you umount /proc)

-      Edit /etc/fstab on the target volume, changing from physical devices to Xen block devices

-      unmount the target volume and stop the physical host

-      create a Xen configuration to go with the target volume, and appropriate kernel/ramdisk

-      "xm create" the new host

 

A few extra steps may be necessary, such as adjusting ifconfig-eth0 for the new MAC address, adding xvc0 to /etc/securetty, etc.

 

This plan lets us partition storage for the virtualization environment however we like.  To keep it simple we often use a single large root partition—Xen does not require a /boot filesystem on a paravirtualized domU unless you use pygrub.

Hi,

 

I am converting few physical machines to xen virtual machines. The virt-p2v requires my physical machines to shut down. These servers are centos / redhat 5.x.  I will be using tap:aio. How do I create an img file from my partitions? some has 1 HDD and some has 2 or more.

 

 

Thanks!

Paras.
