Good day. In some cases (mostly domU crashing or hanging up) xapi on slave is unable to perform some task (f.e. migration). This task appear in task-list as 'pending' and can not be cancelled by normal way. I found single way - to restart master xapi (and slave xapi afterwards) - this clean all pending task queue. But I think it really brute (and not very good, some other tasks may be in progress and they will fail unreasonably). Does XCP support some kind of 'force drop task' operation? During xen kernel researches I very often reproduce this problem and I believe it can be created even on normal (xs) kernel by malicious application with root access. By creating 'unmigrable' state and causing XCP somehow (by excessive memory allocation f.e.) it can cause compromising whole pool instead been kept within single domain. I think this is simply administrative kind of command (forgot task) and does not required to change system/hypervisor code. --- wBR, George. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
