similar to: How do you change XenStore permissions?

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

APIs such as sh_invlpg and sh_update_cr3 take a pointer to the virtual cpu on which it needs to operate as an argument. However, it appears that the call can only operate on the currently executing vcpu. Regards, K.

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?

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

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

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

Hi,I want to watch a xenstore node,when the value of the node is changed I will be noticed. So I use the xswatch function. I use the python template of the http://wiki.xensource.com/xenwiki/XenStoreReference. However, it is weird that when the xenstore node changed, the call back function is never called. Thanks! _______________________________________________ Xen-users mailing list

I just downloaded Xen-4.1.1 from xen.org, compiled it, and installed it. I then compiled kernel 3.0.0 and added the hypervisor and dom0 kernel in a grub 2 entry. After booting, I executed "xl list," to confirm the hypervisor was running. I was greeted with this message: libxl: error: libxl.c:56:libxl_ctx_init Is xenstore daemon running? failed to stat /var/run/xenstored.pid: No such

Hi, I believe I can post this here. I have a domU ( Redhat 6) running in Paravirt mode. When I migrate this domU to another host, looks like the domU is freezing in the other host. When I take it back to original host ,it starts to run normally and this is what can see in dmesg of domU : suspending xenstore... trying to map vcpu_info 0 at ffff88000434b020, mfn b67660, offset 32 cpu 0 using

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

How should I translate he store part of the word XenStroe? Should it be translated like store as shop or store as repository? I myself see it as store in AppStore, so it is somehow like shop, not simply a repository. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

hi, it would be extremely useful for me if someone with knowledge of how the current tools and drivers use Xenstore would be kind enough to update the Wiki with current information. I have been spending quite a lot of time trying to get my domU connected to a block device in dom0 using a home-brewed domain creation tool, and I am still at the ''Timeout connecting to device!''

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.
