Hi, I am writing a small application to watch for xenstore events. I want to know when a specific domain shutdown or reboot. It is best to watch it via xenbus interface, but how? Is there any event or node can give me such an event? If not, I must periodically scan the domains (using libxc interface) to detect if a domain dies, but that is not as good as xenbus approach. Many thanks. Hieu

Hey everyone, I''m trying to write a simple python program in dom0 that registers a watch on the xenstore to determine when a domU has shutdown. Is there a particular token I should use? Looking through the tools/python/xen/*.py code, I''ve come across the ''control/shutdown'' token... seems promising? My code is attached below. As is, if fails to call the

Hello!. How can i use @releaseDomain from dom0 to subscribe for domain destruction? I''m try to add watch for @releaseDomain path with token equal of needed domain id. But when another domain dies, i get domain that i provide via token to xs_watch. Is that possible to get id of domain what released from xenstore? -- Vasiliy Tolstov, Clodo.ru e-mail: v.tolstov@selfip.ru jabber:

Hi, xstransact and xswatch are well designed python interface that can be used by third party utils rather than only in xend. But the logging approach here binds xswatch to xend and prevent it from being used by other utils. This patch removes the dependency on XendLogging from xswatch.

Hi All. I've updated my system from 6.3 to 6.4. In my /etc/yum.repos.depel.repo I have: [epel] name=Extra Packages for Enterprise Linux - $basearch #baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch mirrorlist= http://mirrors.fedoraproject.org/mirrorlist?repo=epel-6&arch=$basearch failovermethod=priority gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

The VMID field is 8 bits. Rather than allowing only up to 256 VMs per host reboot before things start "acting strange" instead maintain a simple bitmap of used VMIDs and allocate them statically to guests upon creation. This limits us to 256 concurrent VMs which is a reasonable improvement. Eventually we will want a proper scheme to allocate VMIDs on context switch. The existing code

Hi, every one: I had problem creating domU on diskless device by using xen-unstable. Following, please find out details. BTW, the same configuration works fine on device with hard disk (1) Xen, dom0 kernel and dom0 root file system are loaded/mounted over via eth0 (2) DomU root file system is created in a file-backed virtual block device(VBD). The file-backed VBD locates at some directory on

I have written some programs in Common Lisp and I have been using SAS to pipe those programs to my lisp compiler in batch mode by using the %xlog and %xlst SAS commands. I wonder if there is in R a similar way to pipe commands to LISP so that all my work would be concentrated in R even when I have to call a LISP program? I have looked at the foreign library but this seems to adjust data types not

Using the 2.0.6 demo cd image, I booted the supplied freebsd image and rsync''d the file system to an NFS server.

Hi all, What's the best method to send automon call recordings (*1) to the voicemail box of the Asterisk user? Do you have to trap hangups, etc, or is there some global variable that can be set? Thanks! S.

Hi Ewan, I''m almost ready to integrate some PPC-specific stuff into xend, and I was wondering if you had a plan for how that should work. First example: the device tree data structure we talked about a few weeks ago. We will need to pass the config data to PPC code, probably in XendDomainInfo.initDomain(), and then pass the resulting data structure into libxc''s xc_linux_load()

Hi, I tried to issue: xm save VMID FILE, and got the following error: Error: Error: [Failure instance: Traceback: twisted.internet.error.ConnectionRefusedError, Connection was refused by other side: 111: Connection refused. xm create works fine, xend is running on domain 0, I can log in the VM through xm console VMID and ssh without problems. I can also stop and restart the domain.

Maybe this question is a little stupid, but please help me. I am a newbie to Xen. When I tried to create a new domain "domain 1", I followed the Yan-Ching CHU''s guide on :installing quick file systems for new domains in Xen 1.2". But when I do "xc_dom_create.py -Dvmid=1", Xen seems to start to boot with some normal bootup information, but right after several

Hi Xen-users, I am trying to boot of my fist guest domain. The below attached message was thrown on the screen. I am not quite sure that the below information is sufficient to root cause the issue.

Greetings to All. A little background about what I am trying to do, and please excuse the length of this post. I am setting up a voicemail (VM) system based on Asterisk. From what I've heard Vonage uses Asterisk as their VM platform as well. I am running 1.2beta with a MYSQL backend for extensions and VM user info. All the sound files and vm messages are being stored through an NFS

Hi,all, I cannot get my network in domain1 work. Here is my configuration: in dom0: I have two network cards, the ip addrs are 141.213.10.110 and 192.168.0.4, respectively. 141.213.10.110 is an external IP and can access internet directly. The gateway should be 141.213.10.1. /etc/xen/vfp: the domain1 configuration file, I created domain1 using ''xm create vmid=1 -f
