...I am hoping I can get some help with how vCPUs work with weights and caps 1. If I have a domU with 2 vCPUs and a weight of 256, does the weight double (512) or is this 256 time slice across both vCPUs. If the weight does not double, how is it beneficial to have multiple vCPUs? 2. If the domU has 2vCPUs and a cap of 100% how does this work since 100% is a mex of one physical CPU. Thanks, Mohamed

Hello all, I'm jumping into this mailing list because my question still unsolved after Googling the web. Do you know any performance of sizing recommendations about Samba 4.7.1 ? For few informations : 2vCPUs / 1 Core 8Go of RAM 140 simultaneous Windows users / 250 at most 20 NFS shares mounted via fstab This question because my RAM is all eated up in the buffer/cache (normal according to last chapter of : https://wiki.samba.org/index.php/Performance_Tuning). Users are not complaining but I don't...

Hi, This patch intends to accurate vcpu weighting for CPU intensive job. The reason of this problem is that vcpu round-robin queue blocks large weight vcpus by small weight vcpus. For example, we assume following case on 2pcpu environment. (with 4domains (each domain has 2vcpus)) dom1 vcpu0,1 w128 credit 4 dom2 vcpu0,1 w128 credit 4 dom3 vcpu0,1 w256 credit 8 dom4 vcpu0,1 w512 credit 15 d4v0 gets 15ms credit each time. but if 3vcpus are blocking,(like d1v0, d2v0, d3v0) d4v0 credit becomes over 30msec(45msec=15x3times). Then d4v0 credit cleared. This makes d4v0 uses...

...If it has already opened event channel,bind event notification,opened connections to xen successfully when goes to err in xenpaging_init()，how about dealing with these resources such as xenpaging_teardown. 3)We have tested on Win7-32bit about 40vms to start xenpaging at the same time.The vm is 1G 2VCPUS,and we page out 180M.Then we put 80-90% memory pressure on each vm.About one hour later,there happens many BSOD on vms.and most blue screen code is 0x... 7F or 0x...19. We guess some special pages which systems need use to run may be paged out and cause BSOD.and sometimes print out mmio information...

...the time. Start puppet-agent and CPU Usage (on both CPUs in a 2vCPU host) immediately pegs to 40%-60%....stop puppet-agent and it drops to near zero. Is this a known issue? Puppet-agent eating up tons of CPU time (via the ruby interpreter)? This host is a Windows 2008 VMware VM (VSphere 5) with 2vCPUs and 4GB of RAM assigned. It has no CPU or Memory resource limits (set to unlimited). No reservations (set to 0). CPU and memory resource shares are set to "High". VMware Tools are installed, running, and current.
