similar to: [PATCH 2/2] xl: add cpuid parsing and translation

Hi, xl is currently ignoring the cpuid= variable in the config file. As I don''t like the current interface xm exposes (basically because it is complicated, unintuitive and very error prone), I implemented a new scheme for specifying CPUID flags policy, combining QEMU''s and Xen''s approach: cpuid = "<base>,<feature_name>=[01xks]*,... The patch includes a

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,

Hi, the attached patch makes Xen tracing work again, after the introduction of the hypercall buffers broke it. Just a missing line. Thanks to Uwe Dannowski for reporting this.

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, 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

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, this patch introduces a new config file option (numanodes=[x]) to specify a list of valid NUMA nodes for guests. This will extend (but not replace) the recently introduced automatic placement. If several nodes are given, the current algorithm will choose one of them. If none of the given nodes has enough memory, this will fall back to the automatic placement. Signed-off-by: Andre

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

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.

Hi, during some experiments with many guests I get crashing Dom0s because of too less memory. Actually the OOM killer goes ''round and kills random things, preferably qemu-dm''s ;-) The box in question has 128GB of memory, I start with dom0_mem=8192M (or 16384M, doesn''t matter). I also used "dom0_mem=8192M,min:1536M", but that didn''t make any

Hi, while testing some APERF/MPERF semantics I discovered that this feature is enabled in Xen Dom0, but is not reliable. The Linux kernel''s scheduler uses this feature if it sees the CPUID bit, leading to costly RDMSR traps (a few 100,000s during a kernel compile) and bogus values due to VCPU migration during the measurement. The attached patch explicitly disables this CPU capability

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
