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

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:

Dear,Beg for your help. I am really puzzled with this problem.HVM domain can not boot up with Qcow incremental image(using command: qcow-create size incremental_file original_Qcow_img_file), but it can boot up with the original Qcow disk image file. When using Qcow incremental image, the guest qemu window would disappear before loading grub, and `xm list` can not find this guest domain.The VM

Hi, I''m running a two node xen-Cluster with CentOS 5.3. I''m using gfs2 for the cluster filesystem and kernel 2.6.18-128.1.6.el5xen #1 SMP for Dom0 (xen 3.0.3). Live migration works fine as long as the DomU guest is running CentOS 5.3 or SLC 4.7 with kernel version 2.6.9-55.EL.cern. But if the SLC 4.7 guest is running the current 2.6.9-78.0.17.EL.cern kernel, the migration

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?

Hello, I''m running 6.26-2-xen-amd64 with xen-hypervisor-3.2-1-amd64. Now I try to pass through a controller card to WHS, at the moment without success because the card isn''t present in DomU. At the first moment I guess it''s a windows problem ;) so I''d tried to boot a Knoppix .iso but same problem there, the passed through device isn''t present in DomU.
