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 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?

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

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

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!''

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

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

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.

Hi, Can anyone please tell me how to get ".probe" function in "struct xenbus_driver" called? I want to do one simple test of event channel communication between peer modules of domU and dom0. I wrote one backend and one frontend driver (I tried registered as misc/blk/input device) where I put in all my xenbus routines, but cannot get .probe called after insmod my module, I

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

Hi, is it possible to access xenstore through libvirt? Or at least any other programatic means other than calling xenstore-read/write through shell? I understand it is somewhat of a security risk but still... Thanks, Marin

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,
