Here are two patches that let xm create, save and restore extract and preserve elfnotes read by the domain builder. This is handy for a few things. In particular, I''d like it so that xm can decide whether or not guest domains support fast resume (if save fails, or for checkpointing). _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

Hi, This patch series fixes the S3 resume of a domain running xenstored and a frontend over xenbus (xen-netfront in my use case). As device resume is happening before process resume, the xenbus frontend resume is hanging if xenstored is not running, thus causing a deadlock. This patch series is fixing that issue by deferring the xenbus frontend resume when we are running xenstored in that same

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. The first patch modifies creation of the hvmloader key in xenstore and adds creation of a new read/write hvmloader/generation-id-addr key. The second patch changes hvmloader to use the new key (as

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. The vast majority of the code is in second patch. The first patch merely changes the xenstore key name used by hvmloader to store the buffer address.

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

I got latest (13601) yesterday evening. This doesn''t seem to work to do Restore (at least of the Windows test-image that I''ve been using for testing previously). The VM restores reasonably OK, but it jumps to an invalid address shortly after restoring, giving a D1 blue-screen error (DRIVER_IRQL_LESS_OR_EQUAL), which turns out to be "page-fault in driver" after I

Hi Ewan, I''m almost ready to integrate some PPC-specific stuff into xend, and I was wondering if you had a plan for how that should work. First example: the device tree data structure we talked about a few weeks ago. We will need to pass the config data to PPC code, probably in XendDomainInfo.initDomain(), and then pass the resulting data structure into libxc''s xc_linux_load()
