Cannot Set Cpu Affinity On Process Invalid Argument

How is it being verified that it is misbhaving - the kvm process is just not in a proper cpuset?? Why did the best potions master have greasy hair? That said, some notes below. Why do languages require parenthesis around expressions when used with "if" and "while"? Source

It is possible to define metric spaces from pure topological concepts without the need to define a distance function? I add/change the config file with following line. Please help us by testing this new package. However, it's weried to see "cannot set CPU affinity on process 0", how came the PID of domain process being 0?!, could you try to debug with gdb, and to see find this

I just tested it below in a Single node DevStack with today's Nova git with the Nova instance being QEMU emulated, but I cannot reproduce the said failure in this bug Serge Hallyn (serge-hallyn) wrote on 2015-05-01: Re: [Bug 1439280] Re: Libvirt CPU affinity error #26 Can you show 'virsh capabilities' output with both packages?

I wont speak for the Ubuntu developers but I strongly suspect that they'll be unwilling to diverge from upstream. Matt and I just need to verify that the new package is correct (I have no doubt it is) Matt Kassawara (ionosphere80) wrote on 2015-05-15: #51 I'm waiting until the package Because this is a multi-cpu numa machine (hp DL785), I needed to pin the virtual cpus to physical cpus. https://www.redhat.com/archives/libvirt-users/2012-March/msg00201.html I am sorry that I make a wrong file diff.

What's not clear to me is why the Ubuntu version would be adding this line since it sounds like master/kilo-3 is behaving correctly per the spec (only adding these lines where Serge Hallyn (serge-hallyn) wrote on 2015-05-01: #22 I'm a bit confused - what exactly is the bug? In fact, adding the "hw:cpu_policy=shared" to extra_specs in the m1.tiny flavor has no impact on this issue.

Tony Breeds (o-tony) wrote on 2015-05-11: #37 We're in discussions with the libvirt devs to work out if the fix is correct and/or exposes a libvirt bug.

I have only 1 other process running on the core, I have tickless mode enabled in my kernel build, I have rcu callbacks on different threads but it's still not working. For more information on therefore solution and/or where to find the updated files, please follow the link below. If no cpuset like (cpuset='0-10,^9') is specified, the domain process will be pinned to all the available pysical process.

I meet this issue too.

For example, if I try to rebind the watchdog process, I get the following: # taskset -pc 0 207 pid 207's current affinity list: 0 sched_setaffinity: Invalid argument failed to set It therefore should not introduce any regressions. 4. Same qemu environment as I noted in my 4-23 post.
