Currently PVHVM Linux guests after ddacf5ef684a "xen/pv-on-hvm kexec: add xs_reset_watches to shutdown watches from old kernel" hang when run against oxenstored because it does not handle the unknown XS_RESET_WATCHES operation and does not reply. The symptom of this issue is a hang during boot at this point: cpu 1 spinlock event irq 70 CPU 1 irqstacks, hard=dec94000 soft=dec96000 Booting Node 0, Processors #1 smpboot cpu 1: start_ip =...

Hi, recently on irc channel (##xen) was some "discussion" about xen vs kvm... There was idea that it would be nice if domUs could survive dom0 restart, but this needs, for example, to have xenstored running in separate domain. In 2009 Alex Zeffertt posted some patches (http://lists.xensource.com/archives/html/xen-devel/2009-04/msg00696.html) to add this functionallity, but they

By default, /var/lib/xenstored is mounted tmpfs in centos 5 but this doesn't appear to be true for Xen4CentOS. This can cause performance issues as mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=446089 I'm not sure if this should be part of xencommons, but if not, adding a tmpfs mount should probably be documented on the quick start wiki page. Thanks, Sarah

The contents are the wip.testme branch currently on salsa. I combined the wip.initscript and wip.oxenstored into this and added more things today. I think this is pretty gtg and it's smoke tested (in several cases by scping files around instead of doing package build), so it needs a final extra review and test round before putting it in master branch (which I don't want to force push). I redid...

...o make install-stubdom Xen installed and I got xen-4.5-unstable.gz in the /boot. I have to say that I'm using PXE boot to boot CentOS. Bridged networking and nfs rootfs works great thanks to Dracut. I booted xen with PXE boot. It was not a problem. xl dmesg shows usual xen boot log. But. The oxenstored is not starting. Simple sudo xl list just hangs. I looked at the /var/log/messages and found there some bad looking messages.

...ount should probably be documented on the quick start wiki page. Sarah, Thanks for looking into this. Adding a tmpfs mount to xencommons, if using the C xenstored, might be a good idea -- I'll float that with upstream and see what they say. As an alternate, can you try using the ocaml-based oxenstored (which doesn't use the filesystem as its atomicity mechanism)? To use oxenstored: * Install the xen-ocaml package * Reboot dom0 * Verify that oxenstored is running: # ps ax | grep xenstore 654 ? S 0:00 /usr/sbin/oxenstored --pid-file /var/run/xenstored.pid (On my to-do list is...

When a message with zero length is sent to xenstore, the body of the message was not processed until the socket or ring had more data to read; this will cause deadlocks if the requestor is waiting on a response to continue.

Hello all, I am trying to get a xenstore/oxenstore (oxenstore is mirage based) stubdom to get to work on Xen 4.2.1. I know that I need to set XSM/FLASK rules and so I have compiled 4.2.1 with XSM and FLASK. I already talked with Daniel de Graaf (on the mailinglists) and Steven Maresca on IRC about this thing. Daniel already wrote a XSM/FLASK rul...

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
