similar to: Creating a custom variable in xenstore from dom0

Hello. Is it available a communication interface between Dom0 and DomU to get some parameteres about DomU without connection via ssh? For example i need to get information about IP addresses that are allocated in DomU. I found following mail-thread: http://xen.1045712.n5.nabble.com/How-to-get-domU-IP-address-td2510278.html Keir Fraser said about xenstore, but as i understand to use xenstore

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

On some production servers with dom0 kernel 2.6.32 pvops and xen 4.0 and domus mainly windows with gplpv I noticed a strange cpu usage by the dom0 mainly with the use of a single cpu, for example this take from one server: xm vcpu-list Name ID VCPU CPU State Time(s) CPU Affinity ... Domain-0 0 0 3 -b- 1043377.5 any cpu

Dear All, I have a problem with my VPS machine ...I used Centos OS and xen application : - I created domU called vps1 with this configuration : # more /etc/xen/vps1 kernel = "/usr/lib/xen/boot/hvmloader" builder = ''hvm'' memory = 1536 name = "vps1" vif = [ ''bridge=xenbr0,ip=202.162.218.236,mac=00:16:3E:12:18:36'' ] disk = [

Hi, I want to know how everything communicates with XenStore. Do domUs use the front-end/back-end driver to dom0 and then the back-end driver contacts xenstored? In particular, how do the xenstore-* commands work on a dom0 and domU? And when should unix-domain sockets be used to communicate with xenstored? Thanks, Hayawardh _______________________________________________ Xen-users mailing

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

I use xen 4.0(dom0 is suse11.sp1,2.6.32 x86_64) on Dell R710 with PERC H700 RAID adapter. --Intel(R) Xeon(R) CPU E5620 @ 2.40GHz --8 CPU cores. --Memory 64G --RAID5 4.5T When I dedicated (pin) a CPU core only for dom0 use.

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, 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

Package: xenstore-utils Version: 4.0.1-2 all it says is: "Description: Xenstore utilities for Xen This package contains the Xenstore utilities." Wow, i never would have guessed that a package called xenstore-utils might contain Xenstore utilities. I'm glad that's cleared up! that just leaves a few tiny, niggling questions: 1. WTF are the Xenstore utilities? 2. What are

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

Hi, Xen wiki states that using linux 3.0 and above as dom0 works with all graphics cards. I could install the fglrx graphics driver on my desktop machine with a discrete graphics card (Radeon HD 5870), but I see a blank screen while loading fglrx on my AMD Fusion E350 machine with integrated graphics card (Radeon HD 6310). The graphics driver loads fine when the Linux kernel runs alone not as

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.
