similar to: domU configs for virt-manager

I had an issue late yesterday where some windows domU''s were down. The person who "owns" those domUs let windows updates install and then restart, which they failed to restart. When I tried to manually restart them I was getting can''t allocate memory errors. In the past I''ve had can''t allocate memory errors when trying to bring up a new domU.

What have I done wrong? I installed an xp (service pack 2) domU using the virt-install example from the man page, on a zfs volume. I noticed this behavior on build 129, and I replicated the behavior on build 130: root@opensolaris:/tmp# virsh version Compiled against library: libvir 0.7.0 Using library: libvir 0.7.0 Using API: Xen 3.0.1 Running hypervisor: Xen 3.4 root@opensolaris:/tmp#

Hi all, I would like to know how to debug xen. To give some more informations, I would like to explain why I''d like to do this. I''ve compiled xen from source (3.1.x/unstable) and installed it on Debain etch. Furthermore I''ve installed 2 DomU, one HVM (Win2k3) and one EFW (Endian Firewall, RH-based 2.6.9-55 kernel). Both DomU''s are running fine for about 15

Dear Xen Community, today we tried to upgrade our base server from a Xeon E5430 to a Xeon X5570 (Nehalem). This worked fine so far, but our DomUs with Kernel 2.6.27 no longer boot - they start up until the following message appears: [..] Mount-cache hash table entries: 256 Initializing cgroup subsys ns Initializing cgroup subsys cpuacct Initializing cgroup subsys memory Initializing cgroup

Hello list! I''ve noticed this problem a couple of times now.. so I''m wondering if it''s a known bug? Symptoms: After "long" dom0 uptime (174 days when it happened now, was something similar on previous times too) cannot start new pv domUs anymore.. pygrub runs and boots the kernel, but kernel newer gets to actually running initrd and the console output

I''m creating a new domU using ''virsh create <xmlfile>'' without specifying the MAC address within the XML file, under the assumption that the dom0 or hypervisor generates the MAC address for me. Next I''d like to get the MAC address that was assigned to this new domU, and I don''t see a way to get that information from the command line via virsh

i installed an HVM WinXP-SP2 (english) on a xen-3.2.1 @ fedora-core8. if I try to connect to the RDP-port, the winxp-DomU freeze for about 10 seconds (can''t make any action on the vnc-viewer, all running programs do not update there view (e.g. windows clock does not run) and the "xm top" shows me 100% CPU load on this domain. After this 10 seconds, I got the normal rdp-login

I''m running Xen on Nexenta Core, and I haven''t yet figured out how to control which DomU''s are started with svcadm enable svc:/system/xvm/domains:default. virsh doesn''t seem to be available with Nexenta Core, so I''d rather edit the configuration files by hand. However, I''ve found neither OpenSolaris or Nexenta documentation on how this is

Hello all, I have a CentOS Dom0 booting CentOS DomU, I am able to start multiple DomUs from the command line using xm create, but if I copy the configuration files to /etc/xen/auto only one of the DomUs seem to start up automatically. Has anyone experienced anything similar before? Any pointers / hints? Thanks. -- "I never look back darling, it distracts from the now", Edna Mode

The main Xen mailing list ("xen-users") generally advises users to limit the memory on dom0 to 2Gb or less. Apparently the general version of Xen has troubles with this. What''s the corresponding advice for the Xen in OpenSolaris, Nevada b87 in particular? I''ve got an X4600 with 32Gb of physical memory on it. I was originally planning to have dom0 be the general-

Hey all, I was watching some logs on a domU today and i suddenly noticed that the timestamps were off by something on the order of 47 seconds. I was surprised because *I don''t* run independent wall clocks. I checked some other domUs and the "drift" was also very close to that of the first domU. I also checked another dom0, Here the domUs were "only" out of sync by

Hello all fellow CentOS users! I have a working xen setup with 3 paravirt domUs and one Windblows 2003 fully virt domU. There are to virtual networks. As far as I can tell in the paravirt Linux DomUs I have gigabit networking, but not in the fully virt Windows 2003 domU.... Is there a setting for this, or is it not yet supported? I run xen-3.0.3-64.el5_2.3 Kind regards, Coert

Hi, I use a EQ 4 dedicated root server by hetzner with ubuntu jaunty. I installed xen 3.3 with debian kernel and brought up 3 domUs. Now comes networking... Hetzner does not allow bridged networking so I have to use routed mode in xen. No Problem so far, but the Problem actually is: When I bring up a domU the routing table is created by the xen-script vif-routing. The network interface name

Was setting up 2 domUs on the same xen machine. Is there any benefit in using the same bridge vs. two separate bridges (one for each domU) incases where we are interested in only domU-domU network traffic? What will be the preferred configuration? thanks in advance, harish _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

Hi, i''m running a two dom0 nodes cluster for HA, and xen domUs running on top, currently it handles 5 domUs. The issue is that there''s a domU that can only run on one node, it''s not possible to start it on the other one. I get a ''b'' status and can''t access the console. Other domUs can start in either node and I can access their console without

Hi all, I have a Sun x2200 named Adra running OpenSolaris 2008.11 set up as a Dom0 per Levon''s instructions on this site. It hosts some production services and has been running nice and stable for a number of months now (with NetWare DomUs running GroupWise, believe it or not). The machine is pretty nicely speced out and there''s room for more virtualisation, so I was

Chaps, Perhaps this question is a little basic for this list but I''m not really sure of the simplest method or best tool for the job. I''ve created some images with `dd=/dev/zero ....` and I''m using them for the domUs now. Some of them have been running for a few months with no probs. Trouble is that I''d like to create a separate partition within the domU.

Hi All, Fairly new to Debian and Xen but I have a box running with lots of DomUs under Xen2 and it is fine. I have setup a new IBM eServer P4 and loaded Etch and loaded Xen3. It runs up my first DomU beautifully but when I start my second DomU it crashes the PC and reboots. If I comment out the line in /etc/xen/xend-config.sxp (network-script network-bridge) It will run 2 DomUs Have I run
