Hi, Currently libxl removes entries from xenstore "device/" tree only in case of: a) domain destroy (clean all domain directory) b) dom0-initiated device remove But this doesn''t cover all the cases. At least this isn''t done: a) backend domain shutdown, backend-initiated remove b) backend domain destroy (here backend driver doesn''t have chance to signal

Good Afternoon, I''m using XenStore to make an experiment and share values between Dom''s U and Dom0. Since today I''m having problems with more than 300 entries per path. I dont know but last week I haven''t this problem. Anyone know the limitation of entries per path on XenStore? When I use it on Dom0 I don''t get any problem. Thanks -- Luciano Barreto

Hello, I''ve modified tools/xenstore/xenstore_client.c to include a new utility, xenstore-chmod. This utility permits developers and administrators to manually change the permissions on arbitrary locations in XenStore from the command line. This is often helpful if you''re trying to debug an application that relies on XenStore and is encountering difficulties with permissions.

Hi, for debugging purposes I would like to see the existing xenstore watches and the waiters for the watch. The problem is, we got a EEXIST from xenstored while trying to set a watch from our guest. Is there a possibility to see this on the running xenstored? Thanks. Dietmar. -- Company details: http://ts.fujitsu.com/imprint.html

I''m looking for what I need to write to xenstore from a VM to say whether or not it supports migration and/or suspension. On older versions of NetBSD, suspend/migration isn''t supported and on newer versions it still has issues. Therefore I want to let the XenServer toolstack, etc. not offer the option to the end user. -- Stephen

Hi All , I am using xen 3.2.0 which i have built form source ,I could initially boot Dom 0 and some DomUs. But today when i tried to boot a DomU with birdge enabled it didnt work giving an error .... Error: Device 0 (vif) could not be connected. Hotplug scripts not working. After that I checked my var/log/messages and It gave lots of xenstore-write

After a few times of building xen by source, I can''t start domU anyway. I tried "yum erase xen kernel-xen" and "yum install xen kernel-xen" again, but the problem is still exist. There are xenstore-write errors in /var/log/xen/xen-hotplug.log: xenstore-write: could not write path backend/vbd/1/2050/hotplug-error xenstore-write: could not write path

Hello, I noticed a strace delay when running "virsh list" on my Xen-4.1.3 test server. On further investigation I noticed that in XenStore there were multiple /vm/$UUID entries suffixed by -$VERSION, especially I hat 16 entries for my dom0. For each reboot of the host I get a new entry. After disabling Xend I get the following output after a reboot: > root at xen5:~# xenstore-ls

Hey, I am new to Xen. Recently I have some problems about using xenstore to setup communication between Dom 0 and Dom U. I have successfully installed Xen on Centos 6 and launch a Dom U with Centos 5. "xm" and "virsh" works fine on my machine. I can also use comments for xenstore to access values in Dom 0, such as xenstore-list, xenstore-read, and xenstore-write. But I

The attached patches enable the xenstore client utilities (xenstore-read/write and friends) to be built statically and against uclibc. This is useful for utility domains where a small userspace is desired. Both static building with glibc and linking with uclibc seem to have problems with threading and so the static version of the library is built without thread support. This is OK since none of
