how can you boot an existing linux domU off the cdrom on sles11 dom0?
I have a sles10 domU running on a sles11 dom0. xen is version 3.4. We''re trying to pass through a scsi card to the domU. We assign the domU the scsi card through virt manager. When we try to boot the domU it won''t boot. We need to update fstab and menu.lst, but we need to boot with the hardware attached to see how it''s being seen by the domU. On a physical machine we

should restarting xend restart all the domU''s?
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.

Xen and I/O Intensive Loads
Hi, folks, I''m attempting to run an e-mail server on Xen. The e-mail system is Novell GroupWise, and it serves about 250 users. The disk volume for the e-mail is on my SAN, and I''ve attached the FC LUN to my Xen host, then used the "phy:/dev..." method to forward the disk through to the domU. I''m running into an issue with high I/O wait on the box (~250%)

tap:aio not working...
I''m running SLES10 SP1 and have been using file:/ for my file-backed domUs. The domUs sit on a shared OCFS2 SAN-backed filesystem and are run on my three or four XEN servers. I''m having issues with the loopback devices not being released when the domUs shutdown or migrate, so I decided to switch over to tap:aio for my file-backed domUs. This isn''t working, either.

GPLPV or other drivers for win2k8r2?
Hi. I have some new 64bit Windows 2008 R2 domU''s running on SLES11/xen_3.4.2. What is everyone using to get 1gb network performance on win2k8? I''ve used GPLPV on win2k3, but I see you have to sign the drivers yourself for 64bit. Maybe that process isn''t difficult, I only glance at the link from gplpv''s page. What is everyone using? GPLPV is about the only

SLES10SP2 (xen 3.2.x) vs SLES11 (xen 3.4.x)
I built a couple new servers on SLES11 because I needed to use USB. Since SLES11 has xen 3.4 packages that seemed like the way to go. I''m questioning the stability of the two new servers compared to my SLES10SP2 servers. I''m also questioning the performance of Windows domUs. On Thanksgiving day one of my SLES11 servers running 7-8 domUs crashed and restarted three times. Being

Limited number of phy disks?
In my experiments with setting up a NAS as a VM, I can only successfully import three drives; the root drive, the cd and one more. However, I have plenty that I want to use: disk=[''file:/vserver/vm_disks/Patch.disk.xm,hda,w'', ''phy:/dev/sda,ioemu:hdd,w'', ''phy:/dev/sdb,ioemu:hde,w'', ''phy:sdc,ioemu:hdf,w'',

Resize NPIV Block Device
I''m using Xen with SLES10 and am using NPIV to attach FC SAN disks to my domUs. I''ve resize one of the disks on my SAN and I''m wondering if there''s a way to force Xen to rescan/resize the block device without shutting down the domU or unmounting the volume.

Problem with some win3k3 domUs since crash
Yesterday all of my xen servers went down hard and also lost connection to ocfs2. 95% of the domU''s came back up ok, but I do have problems with a few windows domUs. They seem to start ok, but them immediately lose connection to the network. If I have them on DHCP they are on long enough to get an address, then they lose connection. If I look at the properties of the NIC it says 1GB

Ballooning on SLES11SP1
We have some test servers running SLES11SP1 and we''ve updated to the latest kernel from Novell: 2.6.32.13-0.5-xen Since running the updates on these servers our xen ballooning parameters are not working. Because of memory problems in the past we set dom0 to 2048 meg of ram in grub and set the following parameters in /etc/xen/xend-config.sxp: (dom0-min-mem 2048) (enable-dom0-ballooning

Easy way to replace gPXE ROM?
This may be a better question for the Xen-Devel list, but I''ll start here... Does anyone know if there is any easy way to replace the gPXE ROM with a newer version in Xen? Also, anyone know if there are any plans to have some sort of option in the domU config file to specify a boot rom? Looks like qemu-dm has an "-option-rom" option - is there any way in Xen to make use of

xen 3.2.1 + intel quad core + 8gigs of ram + linux
Hi! Anyone have a suggestion which version of Linux would be the best host? We typically use Ubuntu but we are flexible since we want the best performance and the least amount of headaches getting it installed and working.

how does hypervisor isolates DomU from Dom0

GPL PV TAP cow incompatible?
Hi Is it true that the GPLPV drivers is incompatible with QCOW images? The Windows DomU works fine with raw standard "file:/" images, and paravirtualized Linux DomU works fine with QCOW and raw images. If i use QCOW images with my Windows DomU''s i get a stop error: 0x00000007b (inaccessible boot device). It looks like the blkback.3.hda process, that normally starts with

Trying to Run OpenSolaris PV
Hey, everyone, I''m running Xen 3.2 (SLES10) and trying to get an OpenSolaris PV domU to run correctly. I''ve followed a couple of the instruction sets out on the Xen wiki and other folks blogs, but I''m running into an issue with the domU crashing. The OpenSolaris version is the latest development release - 5.11-0.128. The config looks like this:
