Hi All, I''ve put up a page on the XenSource wiki detailing my progress with dm-userspace, towards the goal of providing flexible multi-format CoW support for Linux and Xen: http://wiki.xensource.com/xenwiki/DmUserspace Currently, the code has a few bugs that I''m working to get cleaned up, but it runs reasonably well enough for basic testing. Any help, testing, feeback, etc would be appreciated. -- Dan Smith IBM Linux Technology Center Open Hypervisor Team email: danms@us.ibm.com _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Sweet! Any estimate on how long much work is left until you could use this to support COW devices within Xen? Are there specific areas that people could help with to speed things along? My favorite thing about QEMU is snapshotting. I''ve xm destroy''d a domain more than a few times and hosed things up. I''d love to have snapshot support within Xen.

Right now, I''m working out some race conditions and locking issues in the kernel module that usually cause problems during stress testing.

Right now, the included testsuite runs fine for me on vanilla kernels, but deadlocks on xen kernels. I''ve heard the opposite from someone else, so feedback on varied hardware and configurations would good :) -- Dan Smith IBM Linux Technology Center Open Hypervisor Team email: danms@us.ibm.com _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
