Hello, I build and installed Xen (4.1.3) from source, and I think I have got it working. Well, almost. I am using unmodified kernel of Fedora16 as my dom0 kernel. So this is what happened. I am able to boot into Xen, but the "xl info" failed with the standard error message mentioned in the tutorial. "libxl: error: libxl.c:56:libxl_ctx_init Is xenstore daemon running? failed to

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]. [1] http://lists.xen.org/archives/html/xen-users/2012-11/msg00111.html -- Peter Viskup

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

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-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

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. --

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?

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

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

Package: xen-utils-4.0 Version: 4.0.1-2 Hi, When you change XENCONSOLED_ARGS in /etc/default/xend, there's no normal way to apply it. Even if you do '/etc/init.d/xend stop', that doesn't stop xenconsoled, despite the fact the analogous 'start' action did start it. There isn't even a separate init script action to stop it, it has to be killed manually. Same goes for

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

(Sorry, lost Keir''s mail). I''m unclear on why we have to have the mapping part of solving the xendev problem. Can''t we just allocate a transaction as usual if we see an ID without a transaction existing, mark it as pre-fail, and when we see the transaction end, discard the copy as if it had raced? Surely the ID lookup is guaranteed to fail in the circumstances we care

Hi , Are there any options with xenstored to access xenstore ? Can I look up contents of xenstore ? Thanks, Sanket _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hello all; While configuring a new VM on Xen today, we managed to tickle some sort of bug that caused xenstored to die, resulting in loads of Bad File Descriptor. Is this is a known issue, and if so, would attempting to reproduce it help?

Hello, I am running a mail benchmark test using smtp-source[1] with VM running postfix on Xen hypervisor. My system configuration is: uname -a -> Linux cadlab 3.1.10-1.19-xen #1 SMP Mon Feb 25 10:32:50 UTC 2013 (f0b13a3) x86_64 x86_64 x86_64 GNU/Linux I am observing a very high disk write usage by xenstored (some 5 Mbps) without even anything running on the VM. Is it normal? During test, I
