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

Waay back at the end of 3.0.3 dev cycle I brought up the issue of XenD running far too many xenstore transactions per-request http://lists.xensource.com/archives/html/xen-devel/2006-10/msg00487.html Short summary: # nc -U /var/lib/xend/xend-socket GET /xend/domain/test Resulted in approx 16 xenstore transactions for a domain with one disk and one NIC - this increases as # of devices

Hi, I''d be very interested to hear: does anyone have a stable working amd64 machine (in 64bit mode)? if so, which kernel do you use, and which version of xen / hg tree do you use? linux-2.6-xen.hg compiles fine over here, but reboots during boot. so fast I can''t see anything. (sorry, my laptop has no serial port. so I can''t capture a log file.) 2.6.16-rc4-git8 plus

Package: xen-hypervisor-4.3-amd64 Version: 4.3.0-3+b1 Severity: critical File: xen-hypervisor-4.3-amd Justification: breaks the whole system Dear Maintainer, Installation is a minimal system designed only to get dom0 working. The following are the uncommented GRUB commands GRUB_DEFAULT=0 GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`

I think this is likely a bug with either mount or glusterfs: [root at vm-container-0-0 ~]# cat /etc/fstab LABEL=/ / ext3 defaults 1 1 LABEL=/state/partition /state/partition1 ext3 defaults 1 2 LABEL=/var /var ext3 defaults 1 2 tmpfs /dev/shm tmpfs defaults

As any other daemon, I''d assume it should be possible to restart xenstored (i.e. if it crashed or if, during development, a fix was made to it that needs to be tested). However, as I learned after over a day of digging, things don''t work anymore after doing so: Since the watches are transient, they''re lost with the daemon going away. Right now I specifically need this in

I''ve been trying to track down just why talking to XenD is resulting in so much CPU time being comsumed by both xend & xenstored. As a test case, I''m running ''virsh dominfo demo'' which results in a single HTTP request to Xend to fetch domain info, eg ''GET /xend/domains/demo'' Run this in a tight loop & I''ll see xenstored

Package: xen-utils-common Version: 4.0.0-1 Consider removal of xenstored tdb file (located at /var/lib/xenstored/tdb) before start of xenstored daemon during the boot (or removal during the shutdown/reboot of the server) as proposed by Ian Campbell during our discussions [1].

I just downloaded Xen-4.1.1 from xen.org, compiled it, and installed it. I then compiled kernel 3.0.0 and added the hypervisor and dom0 kernel in a grub 2 entry. After booting, I executed "xl list," to confirm the hypervisor was running. I was greeted with this message: libxl: error: libxl.c:56:libxl_ctx_init Is xenstore daemon running? failed to stat /var/run/xenstored.pid: No such

And how should the init script deal with that? If they specify an absolute path, it should be used. Eg, /home/alice/Xen/xen/tools/xenstore/xenstore If the user specifies /bin/bash

Package: xen-utils-4.1 Version: 4.1.3-4 Severity: important Tags: patch Bug presented in sid, with patch attached. Similar bug is also present in stable and testing versions. How to reproduce: Install xen-utils-4.1 in a domU, and run: /etc/init.d/xen start Expected result: xenstored running (or to have any other easy way to get it running within a domU) xenstored is not just something

Package: xen-utils-4.0 Version: 4.0.1-2 Severity: normal Tags: squeeze I have 3 VM running. I have upgraded debian squeeze to 6.0.1 (new kernel package 2.6.32-31) and restarted my server. VM were still running. After reboot I could not start xend service (from init.d). I got following errors: kern.log: Mar 22 15:07:30 router kernel: [53888.212756] xenstored[7232]: segfault at 7fff056b5ff8 ip

Hi, I have been getting the following error (logged in /var/log/xen/xend.log) when I try to migrate a VM from one particular host to the other (the reverse migration works fine). My system was working fine for a long time (i did several migrations in both the directions). I am using Xen-3.4.3 (installed from source code) with CentOS 5.4. I am using drbd to replicate the disks.

Hi all, xend communicates with xenstored using unix domain sockets right? So, would it be possible to convert the unix domain sockets to tcp/ip sockets and let xenstored run on a different machine?

Package: xen-utils-common Version: 3.0.3-0-2 Severity: normal There should be a clean and clearly defined way to restart all the Xen daemons in the case of error. If the file /var/lib/xenstored/tdb is corrupt then you must stop xenstored, rm the file, and then restart it. Currently there is no defined way of doing this so the solution is to kill -9 the process, rm the file, and then reboot. --

Package: xen-utils-3.0-unstable-1 Version: 3.0-unstable+hg11561-1 Severity: grave Justification: renders package unusable with the recent unstable kernel, the evtchn device should be created with major/minor 10, 63. Instead, it's being created with 10, 201. If fixed manually, xenstored will re-create it with the wrong minor number. This causes Xen to be entirely unusable, as xenstored is
