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 all, I''m trying to get a pci card working on a guest os (ast01) on dum0 I hided the pci card w/: # modprobe pciback hide=''(0b:08.0)'' then added this line to the guest os config file (/etc/xen/ast01) pci = [ "0000:08:0e.0" ] Whenever I try to start it fails w/: # xm create ast01 Using config file "/etc/xen/ast01". Error: function takes exactly 4

Some users are hitting this panic in network_alloc_rx_buffers() when running a big network intensive app: /* Check return status of HYPERVISOR_dom_mem_op(). */ if ( rx_mcl[nr_pfns].args[5] != nr_pfns ) panic("Unable to reduce memory reservation\n"); I''m not clear on what is happening here. Are the domains changing size? Which memory reservation is being reduced, xen0 or xenU? All the domains are v2.6.8.1, changeset 1.1331 from Tuesday. David...

I''m tinkering with some code to be able to talk to the hypervisor from Windows, with the ultimate aim to get a usable xenbus. So far I''ve created a driver for the Xen PCI ''device'', and (hopefully) mapped the hypercall space given by the CPUID call... What is the simplest hypercall I can make to get an answer from the hypervisor to tell me that it''s

This patch series restores the use of superpages when restoring or migrating a VM, while retaining efficient batching of 4k pages when superpages are not appropriate or available.

Hi Dan, Jérôme and Jason, below is a series that cleans up the dev_pagemap interface so that it is more easily usable, which removes the need to wrap it in hmm and thus allowing to kill a lot of code Note: this series is on top of Linux 5.2-rc5 and has some minor conflicts with the hmm tree that are easy to resolve.

Hi Dan, Jérôme and Jason, below is a series that cleans up the dev_pagemap interface so that it is more easily usable, which removes the need to wrap it in hmm and thus allowing to kill a lot of code Note: this series is on top of the rdma/hmm branch + the dev_pagemap releas fix series from Dan that went into 5.2-rc5.

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.
