Hello, on my xen host, Debian 5.0 I have few domU''s running, most of them are Lenny''s, a couple is running at Etch (Debian 4.0). All domU''s are running stable except of one (Etch / Debian 4.0).

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

Hi, I have Xen (unstable) on two Debian Sarge 2.4.27 systems, one of which is an nfs server and the other the nfs client. I am trying to set up NFS root so that I can live migrate my domains from one to another. My /etc/exports on N1(10.5.144.29) /myfs1/foo 10.5.144.27(rw,sync,no_root_squash) 10.5.144.29(rw,sync,no_root_squash) 10.5.144.30(rw,sync,no_root_squash) My /hosts.allow on N1

When the XenStore tdb lives persistently and is not cleared between host reboots, Xend (version 3.4 and 4.1) re-creates the domain information located in XenStore below /vm/$UUID. (According to the xen-3.2-commit hg265950e3df69 to fix a problem when locally migrating a domain to the host itself.) When doing so a version number is added to the UUID separated by one dash, which confuses

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?

I''m running Xen 3.0.2 on a system that''s based on Slackware 10.2 as Dom0. DomU is also slackware 10.2. Am using the kernel that came with 3.0.2 - no custom config, just a "make world", etc.. Did have to add grub of course. When I start up xend, I get the following on /var/adm/messages: Apr 23 21:04:11 rc25 kernel: Bridge firewalling registered Apr 23 21:04:11 rc25

Hello, I have 2 Dell 1955 blade servers, running RHEL5-Xen. I''m testing the migrate functionality from one blade to another. I can start the domain, move it to one blade (minor delay/packet loss) and everything is fine. When I try to move it back to the original blade the migration fails and the DomU crashes c1b1 = Blade 1 (192.168.131.201) c1b2 = Blade 2

Hi, this is a repost of a previous question - since then I have tried rebuilding my Xen0 kernel numerous times and trying different configurations, but I haven''t yet ever got a single DomU to boot so I really don''t even know what is supposed to happen, let alone how to start debugging it... Can someone please speculate on how to debug this further? It''s a gentoo
