search for: xs_transaction_start

Seems currently xenstore transaction provides confusing message in different places: a) comment of xs_transaction_start says "You can only have one transaction at any time." However do_transaction_start allows up to 10 transactions created, as long as all other existing transaction channel is idle at the time (conn->transaction == NULL) b) when multiple transactions can be created, xenstore is not r...

.... 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 paths?

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, 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!''

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

The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen console * virtual block
