Hi, I migrate Xen4.0 to XEN4.1, and found XEN4.1 performance is not as good as 4.0.2. xm shutdown takes longer time, control thru libvirt take longer time, and since I''m testing PCI/VGA passthru, the "createdevice: pci" also take around 5~8 seconds comparing to 1 second in XEN4.0.2. below is my configuration, do you have any suggestions to make the performance better?

Hi I m trying to install a full virtualized guest on my dell poweredge 1950 with centos 5.1 64 bits.

Anybody out there running Windows XP, Windows XP SP2 or Windows 2003 server with the default XEN 3.0.3 on Ubuntu Feisty ? Have Ubuntu Feisty Dom0 with a number of Ubuntu 6.1/7.04, Debian and FC6 DomUs all working lovely. But it will not work for any windows versions. The install gets as far as the blue "Setup is Starting Windows" screen. Intel VT extensions are enabled and the F5 trick

Hi! I''m not new to Xen but I''m new to this list. I''m having a truely bizarre problem with Xen bridged networking at the moment. This is a new install, on RHEL4. The symptom is that any domU set up simply fails to talk to anything else. It''s there, and running, and it has an ethernet device, but there''s never any response. After digging through the

Hello, A bit of history ================ 1) I''ve got a normal 2.6.20 x64 Fedora 6 Linux server running several things 2) I''ve downloaded and installed the XenSource Administrator Console for Windows 3) I''ve added 2.6.20-1.2962.fc6xen kernel, xen and vnc packages on my Linux server 4) I rebooted the Linux server, and started xend as per user guide Configuration

I am running Pentium D 930 with 2 gigs of ram. Fedora Core 6 with Xen enabled. I am able to start the install and it goes to the first stage of needing to be rebooted. I restart the Domain and it starts to finalize the windows install. And is fine until it starts asking for serial numbers or computer names. Then all of a sudden the guest freezes. The guest CPU goes to zero and so does the

Hi folks, I''m updating my xen server from a dom0 on debian sarge, using a self compiled xen 3.0.4 and a kernel 2.6.16, to a standard debian etch using the deb packages xen 3.0.3 and kernel 2.6.18. On the old server, all my hvm machines use vnc console and a password is set into xend-config.sxp and it works nice. On the new etch server, with the same hvms and configuration files,

I am running Xen 4.0.1 with a 2.6.18-194.32.1.el5xen CentOS Dom0. I built and installed the Xen binaries from source. The systems boot successfully however I am having issues bring up DomUs.

Hi all, I''m having some problem migrating a simple domU between two hosts. Short question: xm migrate (live or not) fails even though either host is capable of running the VM. Error seems to be: "not a valid guest state file: pfn count read" Long question: I have two boxes (devvmdevvmhost1 and devvmhost2) running xen 3.0.3 (RHEL 5), they are attached to a Dell MD3000 unit

I have several systems running 64bit SLES11SP1. I''m trying to Live Migrate between a couple of them and it''s not working, although the same VM will run on each one starting it manually. The system are not identical. Would one expect migration to work between these two systems? See below. Thanks, James The first system is a ProLiant DL360 G6: Proc 1:2533 MHz Execution

Hi. I've set up a cluster with two Debian 6 nodes, running Xen 4 and libvirt 0.9 (from backports). My VMs run over a DRBD resource, to allow live migration between the nodes. I've successfully tried live migration using xm migrate, now I'd like to make it work using virsh, but cannot make it. Here's the error I'm getting: # virsh migrate efw xen+ssh://10.22.22.152/ error:

When I try to use stubdom-dm in lieu of qemu-dm, the guest domain crashes almost immediately if I specify an emulated NIC (''vif='') in the guest configuration file. If I don''t specify a vif, it works fine. If I use the same configuration with qemu-dm instead of sutbdom-dm, it works fine. Is there some reason QEMU emulated networking doesn''t work with stub domains

Hi, I''m kinda new to XEN stuff, and I''ve been trying to create a fully virtualized guest on CentOS 5.3 for almost 3 months and no luck yet. I approached this process through several methods, one with virt-install and creating config file manually. Following is what happens when I try to create a guest, and I have included qemu-dm and last part of xend.log logs below too.

Hi, we have a couple of nodes based on CentOS 6 and Xen4CentOS. Unfortunately some of these nodes keep crashing frequenly.

After a yum update my two guests that had been shutdown do not start any more. I have two other guests running that seem to work okay but I am now afraid that they won't come up again if I restart them. I am running CentOS5 with kernel 2.6.18-8.1.8.el5xen. Previously I had following xen versions installed: Oct 14 23:45:10 Updated: xen-libs.i386 3.0.3-25.0.4.el5 Oct 14 23:46:05 Updated:

Hello, I want to install a 2003 guest on a Debian Etch with xen binary packages (apt-get install), but through a vnc console (no graphical interface).

So the domain gets created with xm create but no VNC port is displayed: ----- Using config file "2003.hvm". VNC= 1
