Hi, I am posting this message because past 36 hours have been nightmare for me. I finally have solved the problem I by temporarily moving put the xml files from /var/lib/xend directories reboot then xend started. And DomU''s were failing to start the above xml files I kept back and got all DomU''s back. I am very very surprised.I do not have any logical answer to this some one

hello all, it''s my first time ever with xen (or even virtualization in general). I installed Xen 3.2 on top of a Debian Lenny kernel 2.6.26-2-686 via apt-get.

Hi I tried building xen on my IA64 machine. It builds and installs smoothly. But I have not been able to start xend.

This implements a suggestion by Keir to remove the xenbus "ignore state transitions on shutdown" code for kernels without a shutdown callback.

Hi, I''m trying to install Xen on Ubuntu 11.04. I read somewhere (please correct me if this is wrong) that Ubuntu hasn''t had dom0 support since 8.04 LTS, and the recommended action was to grab a dom0-enabled kernel from Debian, so I did. I''m running 2.6.32-5-xen-amd64 and built Xen 4.1.1 from source. After installation and some troubleshooting, I tried to start

Hi All, I just tried a new installation of Ubuntu 10.04 (64bit) + Xen and am having some trouble starting XEN. I am using the latest mercurial checkout (4.0.2-rc2) and the only change I made was to Config.mk to enable building the OCAML version of xenstored. " CONFIG_OCAML_XENSTORED ?= y". I am using the same kernel I built earlier for a similar Ubuntu 10.04-64bit / Xen 4.0.0

Hi, I have recompiled xen-3_3.4.3~rc3-1 in Lenny, together with the 2.6.32-10 kernel. While my dom0 boots without issue under Xen, xend refuses to start. I have cut/past my xend.log is bellow. Is there any reason why a backport of this version of Xen wouldn't work in Lenny? Should I try the already compiled SID binaries in Lenny without trying to build myself? Cheers, Thomas When I start

Hi all, I can''t get xend to start and could do with some help. this is the stock 30.2 release. it was working fine on ubuntu breezy, and since I''ve updated to dapper it''s boned... The odd thing is, if I run the installer, I can start xend ok. but when I reboot it''s broken again. I''m guessing a directory is being deleted by ubuntu at reboot time - is

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

Recent xen uses xenbus to suspend PV-on-HVM guest domain. The related code in the xen-unstable tree will fall into infinite loop when guest domain failed on suspending one or more devices. The patch attached changes the logic, and raises an XendError after 1 minute waiting. The patch also makes use of "control/shutdown" entry in xenstore, allows guest kernel report the failure of the

Hi, I have installed xen3.0.4.1 from source and every thing works well. Now I need to upgrade to xen-unstable.

Hi all, I know that this list isn't for usage and install level questions, but the people at xen-users at lists.xensource.com had no idea of what could be the problem and told me to get hold of a "debian-xen"-type list. Which yours came closest to. :-) My setup is a little bit strange, since i change the motherboard and processor of the system from a K7 to an AMD 64 a couple of

Hi I''m a new xen user. I gather from the mailing lists that this problem occurs with excessive console output. However, I believe dom1 was sitting idle at the login prompt when I noticed top on dom0 was showing python at 99% cpu. xend would not respond to restarts. Reboot fixed it. What debugging output can i give you, if any, if this happens again? sam elstob
