Hello XCI developers, I have a HP6930, downloaded xenclient from the git. And by following the instruction in HOWTO, I could get xenclient boot up fine. I try then to start a guest using xenvm.readme as template and nothing shows on the screen for the guest, although xenops shows 2 doms running. Can you point me to how to start a guest. And also, is the tree downloaded from git enough to arrive

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 everyone, Reposting with after having applied the (minor) fixes suggested by Wei and Jan. Allen, if you can tell us what you think about this, or suggest someone else to ask some feedback to, if you''re no longer involved with VT-d, that would be great! :-) -- As already discussed here [1], dealing with IOMMU faults in interrupt context may cause nasty things to happen, up to

Hello, I have been working on VGA-passthrough in the last month. When Xen was at his version 3.5 there was a few patches to make this work for some graphic cards using the patches developed by Han Weidong and posted here (http://lists.xensource.com/archives/html/xen-devel/2009-08/msg01176.html) and the same patches posted file by file are here

Hello, It looks like upstream linux-2.6.git contains at least the following xen related new features for Linux 2.6.36: - Xen-SWIOTLB support (required for Xen PCI passthru and dom0) - Xen PV-on-HVM drivers - Xen VBD online dynamic resize of guest disks (xvd*) Congratulations! What are the plans for 2.6.37 merge window? I believe at least: - Xen PCI frontend Others? I''m going to
