hi, i''ve been successfully running a headless install of OpenSuse 11.0 + Xen 321 as a Xen Dom0 w/ multiple DomUs for quite awhile ... i just built up a new OpenSuse 11.1 + Xen 331 box. short story -- not working, and not clear as to why not .entirely possible i''ve missed some new config req''ts ... what do I need to do to get xen behaving under 11.1? i''m

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, since pinning the cpu cores to Dom0 and the DomUs the shutdown of the VMs doesn''t work anymore. When shutting down or rebooting a DomU the DomU just freezes after the shutdown process but won''t reboot or stop the DomU. The shutdown itself seems to be complete though. We can reproduce this problem on 4 different servers.

Package: xen-utils-4.0 Version: 4.0.1-5.2 After clean upgrade from Lenny I got xend highly use CPU resources causing domU don't being created - due to timeouts for vifs and vbds (mostly CPU Steal Time was increasing - no iowaits). Tried Xen boot options acpi=noirq|ht without success. Option acpi=off solved that issue, but performance of the server was horrible. The final workaround was to

Hi all, I am experiencing issue on freshly upgraded Debian Squeeze with Xen 4.0.1 from Debian repositories. After upgrade the system with Xen was slow - no iowaits only Steal time was high. I tried workarounds regarding ACPI - only acpi=off was working but the performance decrease was quite large due to only one CPU core was active at that time. The last workaround I am running right now is to

Hi my server crashes every 90 minutes. There is no helpfull message in any logfile, the only thing i can see is that smbd consumes 100% CPU. The server hangs completely, no access to console, no networking. This might have something to do with user logout. This server stands in a school and about 150 pupils log out after each lesson. I assume it has nothing to with printing, as printing

One of my test domUs is a opensuse 10.3 PV domain, and it has a /boot/grub/menu.lst file. pygrub is used as bootloader. With xVM 3.1.4, the arrow keys can be used in the pygrub screen. With xVM 3.3-unstable, the arrow keys don''t work for me any more. What I''ve found out so far is that: - gnome-terminal, xterm or dtterm are running with "vt100 application key

Hi, I have a Xen server running OpenSuSE 10.2, with Xen version 3.0.3_11774. It''s happily hosting two DomU''s running the same OS / kernel. Now I tried to create a new DomU running a newer OS - OpenSuSE 11.1. It comes with Xen version 3.3.1_18494_03. Unfortunately for me, it doesn''t work - this is what I get: > xen1:/etc/xen/vm # xm create NEW > Using config file

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.

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.

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

Hi: Reading Red Hat''s Website and a printed manual of RH184 (Red Hat Virtualization course) I see that RHEL 5 only supports RHEL 4.5 and RHEL 5 as paravirtualized guests. So I asume this is the same situation for CentOS 5, right? What''s the dependency between Xen versions for paravirtualized guests? I ask this questions because I got this experiences: 1. Running CentOS 5 as

i''ve external storage (2 x 1TB drives) attached via a Multilane SATA + RAID card (driver:sata_sil24). my goal is a file server in DomU, serving files from a RAID array of the two drives. my Dom0, fwiw, is OpenSuse 11.1. 3 types of file service will be provided: - large, media files will be served to the LAN - active data files will be served to other DomUs over a private bridge - a

Hi All, When I was tring to use Yast(Opensuse 11.1) to Create Virtual Machine, Yast can start the virtual machine installation process but cannot find any disk, so the installation fails. I encountered the same problem when installing Windows XP and Opensuse. Do I need to create a virtualized disk first? Or how can I specify which disk to install? Any help would be greatly appreciated. Eddie

Hi, I''m new to Xen and I''ve set up a few domUs using Debian (I suspect there may be a problem there, see at end). To begin with everything worked OK, I rebooted domUs without any problems, but twice now when I try when I try to restart or shutdown a domain, the xm command locks up. # xm list Error: Device 0 not connected Usage: xm list [options] [Domain, ...] List information
