To make use of the new node aware memop hypercall, the xc_domain_memory_populate_physmap function is extended by a node parameter. Passing XENMEM_DEFAULT_NODE mimics the current behavior.

When dumping heap info (using the Xen console handlers, e.g. CTRL-a) there are entries printed for each node and zone combination. This is helpful, but summarizing the node''s memory usage would be better. This patch adds three lines per node after the heap dump. The first line shows the number of DMA-capable pages, the second one the number of higher pages, the third is the sum of

Hi, the implementation of xl cpupool-numa-split is broken. It basically deals with only one poolid, but there are two to consider: the one from the original root CPUpool, the other from the newly created one. On my machine the current output looks like: root@dosorca:/data/images# xl cpupool-numa-split libxl: error: libxl.c:2803:libxl_create_cpupool Could not create cpupool error on creating

Guys, I''ve successfully ran dom0/domU (both Debian) in my local laptop using 2.6.32.15 dom0 with xen-4.0.1-rc3-pre. Great. Now I want to install it into couple of test-machines without compiling from source.

When I submitted the qcow2 patch for blktap, suggestions came up that the qemu block drivers should be used also for blktap to eliminate the current code duplication in ioemu and blktap. The attached patch adds support for a tap:ioemu pseudo driver. Devices using this driver won''t use tapdisk (containing the code duplication) any more, but will connect to the qemu-dm of the domain.

Hi, if there is no UUID specified in the config file, we generate one during the _parsing_ process. Since xl list -l parses the config file again, the UUID will be generated again in this case and the reported version does probably not match the used one. Fix this by retrieving the UUID from dominfo (like xl list -v does). Signed-off-by: Andre Przywara <andre.przywara@amd.com> Regards,

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, currently we go through the emulator every time a HVM guest does an I/O port access (in/out). This is unnecessary most of the times, as both VMX and SVM provide all the necessary information already in the VMCS/VMCB. String instructions are not covered by this shortcut, but they are quite rare and we would need to access the guest memory anyway. This patch decodes the information from

Hi, although advertised via the usage output, xl cpupool-list -l just returns ERROR_NI, which does not show up on the console. Instead the output is empty, which is not exactly what --long hints to. To avoid confusion remove the line from the help output and just ignore the -l option properly until it gets finally implemented. Signed-off-by: Andre Przywara <andre.przywara@amd.com>

Hi! On BSD, mmap()ing files works on on-disk files but not on pseudo filesystems like kernfs or procfs. Therefore, attached patch mmap()s anonymous memory. Linux equivalents are sysfs and procfs to above BSD''s pseudo-filesystems. On Linux, mmap is implemented for sysfs but it is questionable to me how write operations work since (most) files in sysfs have static content. So this patch

Hi Keir, For HVM guests, all cpuid Fn''s going through domain_cpuid() iterate over the loop and then return 0 for all four registers. Guests OS''s and cpuid tools in HVM which query for cpuid Fn 0000.0000 %eax and 8000.0000 %eax, see the value 0 and think, Xen emulates oldish 386/486 CPUs. This leads to strange boot failures, "your CPU does not support long mode" or
