Hello everyone,
I’m giving virt-p2v a try to see if I can use it to migrate several RHEL physical nodes into XEN guests.
First of all, I apologize for the long message, but I want to provide as many information as I can so somebody might have a clue of what is going on here.
Here’s my test lab: * Test physical node: Dell Optiplex GX270, 512mb ram, 75Gb hd, running CentOS 5.3 (i386) minimal install [root@emerson3 ~]# uname -a Linux emerson3.br.scania.com 2.6.18-128.el5 #1 SMP Wed Jan 21 10:44:23 EST 2009 i686 i686 i386 GNU/Linux
* XEN Host: Dell 2950, 32Gb RAM, connect to a SAN, running CentOS (x86_64) [root@blpc6]# uname -a Linux blpc6.br.scania.com 2.6.18-128.1.1.el5xen #1 SMP Mon Jan 26 14:19:09 EST 2009 x86_64 x86_64 x86_64 GNU/Linux
[root@blpc6]# rpm -qa | grep xen kernel-xen-2.6.18-128.1.1.el5 kmod-gfs-xen-0.1.31-3.el5 xen-libs-3.0.3-80.el5 xen-3.0.3-80.el5 kmod-cmirror-xen-0.1.21-10.el5 kmod-openafs-xen-1.4.8-1.1.2.6.18_128.1.1.el5
Then I downloaded virt-p2v-0.9.9.iso, booted emerson3 off it, answered all question and left the migration to complete overnight. This morning after make sure there was a "migration finished successfully" kind of message on emerson3 console, I connected blpc6 (my XEN host) and entered:
[root@blpc6]# virsh define p2v-emerson3_br_scania_com-200907131614.conf libvir: error : configuration file syntax error: expecting a name Domain emerson3_br_scania_com defined from p2v-emerson3_br_scania_com-200907131614.conf
Although I found the syntax error weird, it created the XEN conf file:
[root@blpc6]# cat /etc/xen/emerson3_br_scania_com name = "emerson3_br_scania_com" uuid = "e955544d84e58d791482e6d8cf4d1da2" maxmem = 2046 memory = 2046 vcpus = 1 builder = "hvm" kernel = "/usr/lib/xen/boot/hvmloader" boot = "c" pae = 1 acpi = 1 apic = 1 localtime = 0 device_model = "/usr/lib64/xen/bin/qemu-dm" sdl = 0 vnc = 1 vncunused = 0 vncdisplay = "-5900" disk = [ "file:/stage/blvd11/p2v-emerson3_br_scania_com-200907131614-hda.img,hda,w" ] vif = [ "mac=00:16:3e:73:c7:15" ]
I decided then to go ahead and try to start the domain:
[root@blpc6]# virsh start emerson3_br_scania_com libvir: error : configuration file syntax error: expecting a name Domain emerson3_br_scania_com started
[root@blpc6]# virsh list Id Name State ---------------------------------- 0 Domain-0 running 113 emerson3_br_scania_com no state
No state?? Have never seen it...
[root@blpc6]# virsh console emerson3_br_scania_com No console available for domain
The machine does not ping after 15 minutes, so I assume it didn’t started ok.
Checking XEN logs:
[root@blpc6]# tail xend.log [2009-07-14 11:07:39 xend 26869] DEBUG (DevController:496) hotplugStatusCallback /local/domain/0/backend/vbd/113/768/hotplug-status.

[root@blpc6]# cat qemu-dm.27016.log domid: 113 qemu: the number of cpus is 1 Watching /local/domain/113/logdirty/next-active /etc/xen/qemu-ifup: could not launch network script Could not initialize device 'tap'
This XEN host is able to start other XEN guests successfully, so network is working fine. I have no idea what TAP device is.
Any clues?
Thanks in advance,
