Which is the Kernel API (Xenbus API) that is available to do a similar action as "xenstore-chmod"?? Thx, Venkat _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

What are the possible cases (I hope there are not many:)) that this Hypercall might fail, HYPERVISOR_event_channel_op(EVTCHNOP_send, &op)???,With an error value of "-ENOSYS (-38)" on a "HVM"?

On Xen-3.3.0, domain0 Megaraid SAS (SAS 1068 controller) driver is not loading correctly if vtd support in Xen is enabled. It fails at the point of initializing firmware. I wasn''t seeing this error with Xen-3.2.2-rc3 (Unstable version), though with vtd disabled in Xen-3.3.0, it is working. Looks like a degrade problem. Any clues? Thx, Venkat

Hello, I''m also seeing this exact same problem. I''ve posted on xen-users, but did not get an answer. Venkat seems to be experiencing the same problem as me. I have the latest BIOS for my motherboard DQ35JO. (BIOS ver 933) I''m running a Q6600 as well. It hangs at "Brought up 4 CPUs." I''ve tried all sorts of combinations of Xen versions and kernels to

This is the error I get while building Xen-3.2.1 when I do a make =============================================== make[2]: Entering directory `/usr/src/xen-3.2.1/tools/check'' LIBXENAPI_BINDINGS=n ACM_SECURITY=n ./chk build Xen CHECK-BUILD Fri Jul 18 11:36:34 IST 2008 Checking check_crypto_lib: OK Checking check_curl: unused, OK Checking check_openssl_devel: *** Check for openssl

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?

After building Xen-3.2.1 I could successfully boot into it if I avoid giving vtd=1 as the boot parameter. If I pass vtd=1 as the boot parameter to xen, the system hangs while booting. The system hangs after the following messages ============================ Boot messages [XEN].....

I was following an email chain in the xen mailing list on HVM hypercalls on grant tables and the email chain link is below http://lists.xensource.com/archives/html/xen-devel/2007-03/msg00688.html This link says that we need not required hypercalls to share memory b/w HVM''s. But as far as my understanding of sharing memory is concerned, I think the memory is shared using grant table

Hi there, I have a Dell T3400 Workstation with CentOS5.1 as dom0. I have hidden a network interface in dom0 to pass it to domU. The domU can come up with the NIC when it''s OS is CentOS5.1 or RHEL5. But when it comes to RedHat4.5 , the NIC can not be found. As I type the command "lspci" in RHEL4.5 domU, it returned: pcilib: Cannot open /proc/bus/pci

I am trying to create a para-virtualized guest with the same kernel image and initrd image as dom0. The configuration is below ================================================================================ kernel = "/boot/vmlinuz-2.6.21.7-3.fc8xen" ramdisk = "/boot/initrd-2.6.21.7-3.fc8xen.img" memory = 428 name = "fedora.fc8" vif = [ '''' ] dhcp =

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?

Hi Venkat., Did you make progress with libmvec? Is there a chance that it lands into clang 11?

I''ve seen some people asking why exposing xenstore attributes via sysfs could be useful. Here''s why I would really like to see such a patch make it into Xen: I''ve been working on getting domU''s to know enough about themselves to be manageable. I require a 128-bit UUID for each domU, and I require that each domU be able to determine its own UUID in userspace.

What are you querying the alias analysis on in the above example - between the load and store? How are you creating your MemoryLocation for those too?

The attached patch: 1. Converts the shutdown driver and xend to use the store instead of control messages, 2. Includes Anthony''s xenstore notification code, and 3. Changes xend so that sysrq''s are no longer sent as "special case" shutdown messages. Store keys are cheap, so making the sysrq delivery less obscure is good. I think I have made all of the
