similar to: DRBD and HVM hosts

Hi, I want to combine all the above mentioned technologies. The Linbit pages warn not to use the drbd: VBD with HVM DomUs. This page however: http://publications.jbfavre.org/virtualisation/cluster-xen-corosync-pacemaker-drbd-ocfs2.en (thank you Jean), simply puts two DRBD devices in dual primary mode and starts Xen DomUs while pointing to the DRBD devices with phy: in the DomU config files.

Hi all, could somebody point me to what is considered a sound way to offer Xen guests on a two node DRBD cluster in combination with Pacemaker? I prefer block devices over images for the DomU''s. I understand that for live migration DRBD 8.3 is needed, but I''m not sure as to what kind of resource agents/technologies are advised (LVM,cLVM, ...) and what kind of DRBD config

Hi, I have been trying to create a xen HVM Centos4.4 image on centos 5 with a DRBD filesystem installing from DVD. However I get an IO error on the filesystem during the centos installation process which then aborts. The DRBD filesystem seem to be setup correctly and is functioning as a block device as I can mkfs -t ext3 /dev/drbd1 read and write without error. If I replace the disk

Hi, I have a running LVM-DRBD-Xen-HVM/Win2k3 cluster-stack under debian/ lenny managed by heartbeat/crm.

Hi, I''ve been building up a new HA system, running Xen on DRBD devices. Configuration this applies to: Debian Lenny xen-linux-system-2.6.26-2-xen-686 package |**|drbd8-modules-2.6.26-2-686 drbd8-modules-2.6.26-2-xen-686 As I''ve been building the system, I ran into an interesting problem, with two symptoms: 1. running VMs would come back up after a reboot, but would hang on

Package: xen-hypervisor-3.2-1-amd64 Version: 3.2.1-2 Severity: important I've a Debian Lenny AMD64 as production server, where it has important HVMs that runs correctly. The problem occurs when i try to create a HVM from a Debian Squeeze AMD64 iso file. At first, the VNC display specified shows perfectly the Debian Installer menu, but when I choose an option (Install or Graphical Install),

Greetings. I''ve reviewed the list archives, particularly the posts from Zakk, on this subject, and found results similar to his. drbd provides a block-drbd script, but with full virtualization, at least on RHEL 5, this does not work; by the time the block script is run, the qemu-dm has already been started. Instead I''ve been simply musing the possibility of keeping the drbd

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I''ve been using xen for a number of years now without issues, but now have a problem. First, the problem: I have a Windows Server 2008 Standard 64bit DomU, I''ve installed a number of applications, and it works quite well and runs stable for weeks at a time so far (ie, has never crashed yet). I tried to install QuickBooks

I''ve installed debian lenny amd64, it is frozen now. I''ve install kernel for xen support but it doesn''t start. It says "you need to load kernel first" but I''ve installed all the packages concerning xen, also packages related to the kernel. Perhaps lenny doesn''t support xen anymore? Any solution?

Hi, i want to install a WinXP as vm, but it won''t work. "xm list" tells me that the winxp-vm is running, but I am not able to connect via vnc. nmap tells me that there is no vnc-port listening and ps -A tells me that qemu-dm does not work. Maybe someone could help me because i have no idea what''s wrong.. System: Debian Lenny XEN: from lenny-repository ps -A says:

Hi, sometimes, especially after a kernel upgrade, I need to reboot the xen host. All the VM''s are mirrored to another machine by using drbd. If the machine comes back after a reboot, the drbd devices are all in secondary mode, and therefore, the VM''s cannot start. I have to issue a "drbdadm primary" for every VM first. (I cannot use "drdadm primary all") Of

Hello all, I''ve just installed a new dom0 with openSUSE 11.3 (x86_64) and I''m seeing domUs crashes when reading from disks. The problem occours when in domU configuration I use memory=1024 maxmem=2048 My setup is DRBD on LVM on Software RAID 10 and drbd devices are used as disks for domUs, using phy:/dev/drbd0,hda,w phy:/dev/drbd1,hdb,w The domU in test is HVM, I''m

Hi guys, I'm looking at the possibility of running a pair of servers with Dovecot LDA/imap/pop3 using internal drives with DRBD and GFS (or other clustered FS) for the mail storage and ext3 for the root drive. I'm currently using maildrop for delivery and Dovecot imap/pop3 with the stores over NFS. I'm looking for better performance but still keeping the HA element I have now with

Hello all, has someone worked with DRBD (http://www.drbd.org) for HA of mail storage? if so, does it have stability issues? comments and experiences are thanked :) Thanks, Rodolfo.

Hi, i wont separate drbd traffic in domU to eth1 interface. What is the best way to do that? I think about make eth1 nic passthrough to my domU. Can i expect some problems with this configuration? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Everyone, I''m trying to get Xen to use a native DRBD device but it seems it will not create the virtual machine. It does not seem to like the DRBD device type, any ideas on what might be wrong? I''m pretty sure my xen config file is OK and the DRBD device looks fine too. Full details below. xm create centostest Using config file "./centostest".

Hello folks, i do not get access to a physical disk with xen. I would like to install windows xp as hvm to the physical partition /dev/sdb1. I partioned the disk with cfdisk. Filesystem type is Linux (83). In my eyes the filesystem using hvm is insignificant(?). I tried the following configurations; probably a lot more than this. #disk = [ ''phy:hda1,hda1,r'' ] (comment from

Hello List, i am new to Centos and did my first install on a server. I got it working that also looks inzo the epel repositorie. Now i want to install DRBD. But yum search drbd returns me only a package i dont need. Do i have to enable the epel-test repo to get it? But test sounds not stable for me and we switched to centos for stability. anyone here can help me or give me any hints on drbd
