similar to: Migrating DomUs from file VBD to LVM Backend

I''m running SLES10 SP1 and have been using file:/ for my file-backed domUs. The domUs sit on a shared OCFS2 SAN-backed filesystem and are run on my three or four XEN servers. I''m having issues with the loopback devices not being released when the domUs shutdown or migrate, so I decided to switch over to tap:aio for my file-backed domUs. This isn''t working, either.

Hello, Can you check following entrys: Old: disk = [''phy:vm_volumes/root.dhcp1,sda1,w'', ''phy:vm_volumes/var.dhcp1,sda2,w'', ''phy:vm_volumes/swap.dhcp1,sda3,w''] New: disk = [''phy:/vm_volumes/root.dhcp1,sda1,w'', ''phy:/vm_volumes/var.dhcp1,sda2,w'',

I have a centos 5.6 server that has xen domUs installed on their on logical volumes. These logical volumes contain their own volume groups and again their own logical volumes. I want to access the domU logical volumes and tried this: [root at kr ~]# fdisk -l /dev/VolGroup00/LogVol02 Disk /dev/VolGroup00/LogVol02: 274.8 GB, 274877906944 bytes 255 heads, 63 sectors/track, 33418 cylinders Units =

Hi Is it true that the GPLPV drivers is incompatible with QCOW images? The Windows DomU works fine with raw standard "file:/" images, and paravirtualized Linux DomU works fine with QCOW and raw images. If i use QCOW images with my Windows DomU''s i get a stop error: 0x00000007b (inaccessible boot device). It looks like the blkback.3.hda process, that normally starts with

Hi List! I've got a problem that I've read about on the web several times now, regarding the uploading of printer drivers to the samba [print$] share. When I try to set the printer driver for an existing printer (HP LaserJet 6L enabled with CUPS) the W2K wizard let me select the driver *.inf file but when finishing I get the well known error message: "Unable to install Intel,

I''ve just made my first ever attempt at an Nullsoft installer, so if you want to try it download "Xen PV Drivers 0.9.5.exe" from http://www.meadowcourt.org/downloads/ The installer should detect the version of windows you are running and install the drivers. At the moment you''ll need to install the shutdown monitor service manually, but you can do that from the start

I''ve been using lvm under centos to create the backing store for domUs and although the performance seems acceptable it has some shortcomings. The biggest of which is the LVM bug which prevents me from removing an lv (it says it is still mounted and it definitely isnt). I thought this was just a centos bug but it appears to be evident in debian and ubuntu too and I really can''t

Hi everyone, Just a quick question: Is there a limit on the vbd size for pv guest domains, I''ve found only rumors on the Internet about a 2TB limit, but from my experience with xen-3.0.3 /linux-kernel-2.6.18-5 (installed from a debian etch packages) I can say that a lvm volume of 3.7TB as created and formated in Dom0 is seen as 1.85TB only of course reporting a corrupted xfs filesystem

Hi, I am trying to recover data from my old system which had LVM. The disk had two partitions - /dev/sda1 (boot, Linux) and /dev/sda2 (Linux LVM). I had taken a backup of both partitions using dd. Now I am booting of CentOS live cd for system restore. I recreated partitions like previous system using fdisk and then used dd to dump all the data onto it. I would like to mount sda2 as LVM, but I

Hello, My name is Fermín Galán. I have started recently to use Xen (so please forgive me in advance if I''m too "newbie" :) and I''m facing my first problems... I''m trying to create a domU, but I''m getting an error: tornado:~# xm create test.cfg -c Using config file "/etc/xen/test.cfg". Error: Device 2049 (vbd) could not be connected.

I have a xen 3.0.2 running on a 733 MHz server, 1 GB RAM. It has two domU domains. dom0 has 512 MB, domUs have 256 MB each. Whenever load average on dom0 is above 1-2 (for example, compressing 200 MB file), I can''t reach any domU domain. Ping replies to domUs take very long time (it''s on LAN), and there are packet losses: 64 bytes from 192.168.11.61: icmp_seq=7 ttl=64

I have an 8-core SuperMicro Xeon server with CentOS 6.3. The OS is installed on a 120 GB SSD connected by SATA, the machine also contains an Areca SAS controller with 24 drives connected. The motherboard is a SuperMicro X9DA7. When I installed the OS, I used the default options, which creates an LVM volume group to contain / and /home, and keeps /boot and /boot/efi outside the volume group.

This is a known issue. It has been fixed in xen unstable. The problem is loop device is not leased after the guest destroyed. If execute "losetup -d /dev/loopX" in domain0, the problem will be solved temporarily. >-----Original Message----- >From: xen-users-bounces@lists.xensource.com >[mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Thomas Karsten >Sent:

Hi I''m using Xen on my AMD64 / Ubuntu 7.10 server which I recently upgraded, and my 2 VMs are decidedly flaky. They seem to be blocked for most of the time, and networking doesn''t work properly. How can I debug this and get them online reliably? Any tips gratefully received! * I can log in via console or ssh, can ping the server''s NICs but can''t ping the
