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:lib...

Since the key information can be fairly simply put on the command-line, there''s no need to require an actual config file. Also improve the help to cross-reference the xlcpupool.cfg manpage.

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 Przyw...

Hi all (and Mr. Dunlap in particular), I have a question about the credit (and ultimately credit2) scheduler that I hope you can help me with. I have read the white paper "Scheduler development update" and as much material on the credit scheduler as I can find, but I am still not completely clear on how I should think about the cap. Example scenario: Server hardware: 2

...really should stick to that. This means domain_update_node_affinity() is wrong when it filters out some stuff from there even in "!auto" mode. This commit fixes that. Of course, this does not mean node-affinity is always honoured (e.g., a vcpu won''t run on a pcpu of a different cpupool) but the necessary logic for taking into account all the possible situations lives in the scheduler code, where it belongs. What could happen without this change is that, under certain circumstances, the node-affinity of a domain may change when the user modifies the vcpu-affinity of the domain...

Hi, list, A VMM provides a VMCS for each VM. How does the VMM assign system resources for each VM? For example, in a multi-core environment, how can I enable the VMM to run, say, on a two-core intel''s processor while I am able to force a VM to execute only on a specific core upon initializing the Guest OS ? that is to say, how I can assure the VM to believe that there is only one physical

Address some credit2 issues. This patch series, along with the recent changes to the cpupools interface, should address some of the strange credit2 instability. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
