Hi I gave the new Xen-4.6rc2 a spin on a CentOS 7 virtualisation guest (nested-xen). I haven't yet started testing guests, but rather looked at the install itself. One issue, I found, was with xenstored.service and the corresponding unit-file: [root at xencen7ws ~]# systemctl status xenstored xenstored.service - The Xen xenstore Loaded: loaded (/usr/lib/systemd/system/xenstored.service; disabled) Active: active (running) since Tue 2015-09-08 23:13:43 CEST; 13min ago Process: 757 Exec...

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 =...

The entries in xenstore have permission attributes. The attributes can be easily altered by xenstore-chmod, however, I cannot find a easy way to see them. I''ve modified xenstore_client.c to raise a new utility. The utility checks the permission and makes an easy-look output. Please tell me any suggestions. Than...

...ould 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 segfault,exact error is attached iniline.

Is it possible to create a custom directory tree inside Xenstore using any of the Xenstore-utilities?? For example, "/local/domain/0/Customdir". Thx, Venkat _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

In our case, this seems to be some kind of bug with xenstored. For example, let's take our servers "vm7" and "vm10" into consideration, which are configured exactly the same, Debian Squeeze vanilla, no backports. "vm7", as stated below, has more Domain-0 entries, but executes virsh commands (f.e. virsh pwd, virsh list etc)...

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, 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 XenSto...

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].

Hi All, I have a machine with three network cards, and the third card(named e1000g2) is in use now. I want to use e1000g2 as default NIC when I create Guest. How can I change the default NIC? I can override the default value of config/default-nic property of svc:/system/xvm/xend. But xend still use e1000g0 when creating Guest. BTW, I can explicitly set "bridge=e1000g2" when creating

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 specifi...

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 specifi...

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.

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 taking > 50% CPU, and XenD taking another...

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 /local/domain/0 > name = "Domain-0"...
