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

I''m trying to do what I think would be relatively simple but can''t seem to make it work. Essentially I want to create several domU''s running CentOS each with it''s own LVM partition for increased performance over image files. Initially I did a test with image files and everything went fine, I booted the supplied initrd and vmlinuz images installed CentOS from

Hello all, I''ve been searching through the archives and the internet for a while now, and can''t seem to find anything that helps me out. I hope you don''t my posting this to both xen-users and linux-lvm simultaneously, but i figured it''d help keep the solution in one place... even though it''ll be the same across two places... Anyways: My setup is this:

Hi All, We''ve limitation of 500 GB per server as per ServerLoft. we are needing to store word/pdf files. We are planning to use following setup. /dev/sda1 - boot - ext2 /dev/sda2 - swap /dev/sda3 - dom0 - ext3 /dev/sda4 - LVM - one LV for each domU, We''re planning 3 DomUs. /dev/sda5 - FreeNAS. Is that possible? Can it be in one of the LVs under 4th partition? Currently, one

Hi all, I''ve got xen-4.1.1 running with linux-3.0.0-rc5 and am trying to start my first guest, f14-x86_64, which does boot on bare metal. The configs below show kernel, ramdisk, and disk assignments for the virtual machine. They also show that the virtual machine uses the target disk devices. The last section shows part of the boot sequence starting with the disk assignments,

Hi all, How can I boot a XEN domU guest into safe mode? One of our servers was forcefully shutdown, and it seems like one of my VM''s could be corrupt, or something. When I boot it up, I get the following on the console: Creating root device. Mounting root filesystem. kjournald starting. Commit interval 5 seconds EXT3-fs: mounted filesystem with ordered data mode. Setting up other

How do I check if the proper sata drivers are being loaded? If they are not what can I do other then rebuilding the kernel? Thank you in advance, Randy _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I need to installa a streaming server for live videos and for video on demand. My choice is red5. Do you think I can use a xen virtual machine to run a streaming service? Or it is better not to virtualize? Sorry for my bad english. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hello, I am currently trying to move my VMs from running on local host storage to a shared storage (trying out iSCSI) but I am facing a bit of a booting dilemma. The domUs are a mix of paravirtualized and fully-virtualized VMs. They all boot and run like clockwork when on local storage. The paravirtualized domUs appear not to have a problem when I relocate and boot them from the shared storage

Hello, I''m not able to mount a HPFS/NTFS domU partition. My system: dom0 is on a debian (Lenny) machine, using xen-hypervisor-3.2-1-i386 Xen Hypervisor. domU is a Windows XP machine, that works well. My target is to mount file system domU machine (when domU is not active). In my domU configuration file I have: disk = [''phy:/dev/virtual_machines/xp_disk,hda,w'',

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

Hi, how can I install a openSuSE 10.3 PV-guest on a LVM-drive of a openSuSE 10.3 host with Xen 3.10? On 10.2 with Xen 3.0.3 the openSuSE-YaST-module for managing VMs could install the system also on block-devices, unfortunately this is not possible anymore with OSS 10.3 :-( What I have tried: - I created two LVM-partitions, one for "/" one for swap. - Installing an OSS 10.2 PV-guest

Hello everybody, I''m playing with Xen and trying to extend DomU disk space. My Configuration: Dom0: all Xen machine are HVM. They''re installed on LVM. I''ve one VG (XEN) on Dom0 and created a LV (here, xps.101.disk) per DomU. disk configuration in xen conf is as follow: disk = [ ''phy:/dev/XEN/xps.%d.disk,ioemu:hda,w'' % (vmid)

Hi list. I''m running Xen 4.0.1 on Debian. I''m trying to live resize a block device : - I have a arbitrary block device in my dom0 (/dev/mapper/vm-vol42). - I start a PV domain with that device as a disk (disk = [''phy:/dev/mapper/vm-vol42,xvda,w'']). - I resize vm-vol42 in the dom0 (adding size only) - the dom0 sees the device''s new size. -

Hi guys! I installed XEN 4.0 on Debian Squeeze but I cannot get the first DomU (not an image) started. Attached you will find /etc/xen/xen1.conf and the result of "xm create -c /etc/xen/xen1.conf" in xen1.log. Can you help me? What did I wrong? Is it about the fstab in xen1 (see also attached)? Many thanks in advance! Regards Stefan

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?
