Hi folks I propose the following changes for 3.1: - Rename source to xen-3. Upstream stripped one part of the version, so the next should be 3.2. - pygrub as extra package. - Rename i386 to i386-nonpae - Rename i386-pae to i386. PAE is upstream default now and pae images works with a 64bit hypervisor. We should think about supporting libvirt. It provides an AFAIK stable interface on the

This patch series adds support for preservation of the VM generation ID buffer address in xenstore across save/restore and migrate, and also code to increment the value in all cases except for migration. Patch 1 modifies the guest ro and rw node creation to an open coding style and cleans up some extraneous node creation. Patch 2 modifies creation of the hvmloader key in xenstore and adds

Hi, George sent a patch on this problem before, but it was not completed. This patch makes libxl use xenbus to communicate with xenstored if libxl cannot open a socket. There''s a place that does not close fd in the case of failure, which is also fixed in this patch. -----------------------------------------Patch------------------------------------------------------ diff -r eff592364826

...t what the DOMID is. When I try to use this technique in the xs_read function, it returns NULL. It works fine if I give the absolute path, but I can''t really do that dynamically since I don''t know the DOMID ahead of time. Basically I''m trying this: struct xs_handle* xs; xs_transaction_t t; void* domid; char temp[] = "domid"; xs = xs_daemon_open(); t = xs_transaction_start(xs); domid = xs_read(xs, t, temp, NULL); Could someone explain why this doesn''t work or maybe let me know of an alternative way to read XenStore in a C application without using absolute path...

This patch series introduces the tapback daemon, the user space daemon that acts as a device''s back-end, essentially most of blkback in user space. The daemon is responsible for coordinating the front-end and tapdisk. It creates tapdisk process as needed, instructs them to connect to/disconnect from the shared ring, and manages the state of the back-end. The shared ring between the

Hi, I''ve installed xen-unstable 4.2 from actual git (last commit was 4dc7dbef5400f0608321d579aebb57f933e8f707). When I start a domU with xm all is fine include the cpu_weight I configured in my domU config. When I start the domU with xl then all my domU have the default cpu_weight of 256 instead of the configured one. Was the name of cpu_weight being changed for xl command ? My domU
