similar to: xenstore permissions

Hi, Is there a way to change the permission for a specific path in XenStore? And can you do that from with in a C program? Thanks Julian _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I understand that "xenstore-chmod XENSTOREPATH perm" will allow xenstore access to each other domains according to the permissions set. But if I need to permit access to a specific domain which will avoid a global permit access, is there a way? Thx, Venkat _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

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,     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,

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. Thanks.

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

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

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

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

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?

Directly including ../tools breaks building in separate object tree, as well as building from mkpatch patch (I believe Rik hit that one). This puts xenstore headers in linux-public.

This patch (fundamentally) adds support to display the full contents of the xenstore directory entries. During some recent testing, the values of interest were always beyond the ..., so I added -w to override truncation. There is a bit of code cleanup as well (snprintf vs. sprintf), one formatting fix, and comments). There is no change to the behavior of xenstore-ls without -w.

Hi all, I installed a Redhat 5.3, and created a VM with guest OS "Redhat AS release 4". Unfortunately, I found that "xenstore-write" doesn''t work any more. For example, #xenstore-write /local/domain/56/vm-data/ipaddress 172.17.15.62 Could not write path /local/domain/56/vm-data/ipaddress From the website, I saw that it is a bug

From: Stefano Stabellini <stefano.stabellini@eu.citrix.com> When disk is a cdrom and the drive is empty the "params" node in xenstore might be missing completely: cope with it instead of segfaulting. Updated in v2: - actually removed the strchr(blkdev->params, '':'') that caused the segfault; - free all the allocated strings from xenstore before returning;

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....? Is there a place within xenstore that anybody can write to and read from? Thanks Julian _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com
