similar to: Xenstore interface works on Windows guest?

Hi, Anyone knows whether how xenstore interface works on the Windows guest? If it does, how? I just want to send a small amount of data between dom0 and the Windows guest.

Hi, I''ve tried to do "xm save" on my Windows XP guest, which runs by ioemu. When I did this, #xm save 6 /xenimages/snapshot1 Error: /usr/lib/xen/bin/xc_save 10 19 6 0 0 0 failed xend.log: [2006-10-06 16:34:22 xend] DEBUG (XendCheckpoint:80) [xc_save]: /usr/lib/xen/bin/xc_save 10 19 6 0 0 0 [2006-10-06 16:34:23 xend] ERROR (XendCheckpoint:227) Couldn''t map

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,     I am tring to write xenstore some information ,so that a guest can read, if i simply xenstore-write /foo "123" in domain 0, guest have not the permission to read this ,and guest domain number are dynamic, so i can not write a program to write /local/domain/X, which X is the domain id i want to export information to, can i ?     So, is there a path (a static path,without domain

I want to create a custom directory something like a/b in the xenstore, i guess there are no domU commands for the same. So how can create this in dom0?

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

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,     I use follow code get xenstore ring and event channel, then i wrapped writing and reading function to operate it ,but it came to oops:     struct xenstore_domain_interface {     char req[XENSTORE_RING_SIZE]; /* Requests to xenstore daemon. */     char rsp[XENSTORE_RING_SIZE]; /* Replies and async watch events. */     XENSTORE_RING_IDX req_cons, req_prod;     XENSTORE_RING_IDX rsp_cons,

Hi : As I want to know the information of the VMs that currently runing on the same physical machine, I''d like to get those VM''s information from xenstore, such as macaddress. Indeed, what I want is IP address, so, if guest can write things to xenstore, I''d like it write its IP address into xenstore and let domain0 reads it directly. So, can anybody tell me whether a PV

Hi, I encountered a problem while porting Solaris as a guest OS on Xen. The problem I found is that when frontend vbd driver get unloaded, it will close the vbd interface by changing the state to XenbusStateClosed. This appears to cause the dom0 hotplug scripts to remove the vbd entry from xenstore for the domU guest, preventing the vbd from being re-attached. So, my questions are: + This

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

I''m looking at building a xenstore-based watchdog, as described at http://lists.xensource.com/archives/html/xen-users/2005-07/msg00597.html However, being somewhat new to xenstore, I''d appreciate some pointers. - What portions of the xenstore namespace should I use? I''m looking for at least two settings writable by the DomUs: A flag to enable/disable the watchdog

i do not know if exist any tool to read a xenstore key previously created from dom0. i want to communicate one domain with another. i started learning Xen one week ago, and i''m very interested in domains communication.

Hi, I was wondering if somebody could help me! I''m trying to write to the xenstore from a domU and read what I have written from inside another domU. I seem to have some permission problems....?

Hi, $subject says pretty much all, this patch updates netfront and makes it store the network addresses of the interfaces in xenstore, so it''s much easier to figure what IP some virtual machine has and (for example) ssh into it. comments?
