PVGrub can''t find config file for domU on logical volume
After hours of googling and not really finding a definitive solution to my problem, I''m a little stuck and would really appreciate some help from others. I have a CentOS 5.4 x86-64 server running Xen 3.3 from the gitco repos as dom0. On this I have created two logical volumes comprising 8GB for the system disk (xvda) and 1.5GB for swap (xvdb). I ran mkfs.ext3 and mkswap on these to

How to Backup and Restore MBR within Logical Volumes?
Hi All, I have several Xen virtual machines within logical volumes using LVM2. I did not use disk images for performance reasons. Conventionally, if I want to clone my virtual machines, I have to dd the LV to an image file. But this consumes a lot of time and harddisk space. So, instead of doing that, I want to use losetup and kpartx with my logical volumes, which contain operating systems of

ISCSI help
I am fairly new to ISCSI and SAN technology but having recently invested in the technology I am trying to find out exactly what can and can not be manipulated, filesystem wise, without requiring a reboot. I am using the inbuilt software ISCSI initiator and multipathing in CentOS 5.1. My steps so far. Create 10GB volume on SAN # iscsiadm -m session -R # fdisk /dev/mapper/mpath0 # kpartx -a

migrate from physical disk problems in xen
I''ve been trying to migrate a win nt 4 machine to a xen domu for the past few months with no success. However, on my current attempt, the original hardware no longer boots, so I''m trying to resolve the issues with xen properly, or else take a long holiday... Anyway, the physical machine had a 9G drive (OS drive), a 147 G drive (not in use) and a 300G drive (all SCSI Ultra320 on

domUloader kernel command line arguments?
domUloader potentially makes my life a lot easier, but from experiments and looking at the code, it doesn''t seem like there is any way to pass kernel command line arguments with it. Am I just missing something? Thanks, John Byrne _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Can you convert Windows LVM domU to sparse img file?
I have a Windows 2000 domU running in an LVM partition. I need to move it to another host, but none of my other xen servers have lvm or free space to create an lvm. So I''d like to convert it to a sparse img file. The file system in the domU is ntfs. Can anyone suggest how to do this?

Success moving Xen LVMs from 32 to 64bit host
Just wanted to share some success I had moving some Xen guests from one server to another. Problem Recap We had Xen host on a single core 32-bit CentOS 5.4 installation on an AMD Athlon 2.1 GhZ system that was giving hard drive errors and needed to move the LVM-backed Xen images to another server. The replacement server was a quad-core AMD Phenom system running 64-bit CentOS 5.4. Our original

what''s correct way of shrinking LVM based domU?
Hi all I want to shrink one of my LVM based domU''s, but don''t quite know how to do it. I have searched the Wiki & HOWTO''s, and they all show you how expand / enlarge a LVM based domU, but not shrinking it. So, I stopped (destroyed) the domU, and then resized it as follows: lvresize /dev/data/cpanel1 -L10GB (It was 100GB), but when I a started it up again, I

Hey folks, I've been getting requests from the users that they want the OCFS2 filesystems aligned to 64k boundaries, however, when I began the project, the dummy of me, created the OCFS2 filesystem on top of the whole disk device (no partition) for example, one of the SAN devices would show up as /dev/dm-10, I created the filesystem using the following command: mkfs.ocfs2 -L SOMELABEL
