Hello everybody, I am a new user discovering libvirt with KVM software. During my first VM creation, I saw an issue with virsh that I can't understand. I wanted to emulate another CPU than the classical qemu32 using virsh. So I used the virsh capabilites command to detect how is detected my CPU host which is an Intel Xeon E5410 and my problem is that this CPU is detected only with the

Hi, ssh: OpenSSH_5.3p1 rsync: 3.0.6 OS: CentOS release 6.3 I got the same problem here, syncing 95M to amazon ec2 without --bwlimit parameter. It should be not caused by cygwin. From 3.0.6 to latest version, I did not find any ssh related problem fixed. After the syncing job is over, ssh process did not quit and consumes 100% CPU. I collected other information, wish it may help. related

Hello, I need to do an intersection between the list elements (partitionslist) and the columns and rows of a matrix (mm), so that the result will be the sums of the rows and columns. Thanks a lot, Romildo Martins Example 1.The Intersection and sum betweeen partitionslist[[1]][[2]] and mm is indicated in bold. 2.The Intersection and sum betweeen partitionslist[[1]][[2]] and mm is indicated in

Hi everybody, I am using Cygwin rsync/ssh to synchronize my files from my home computer to my server. I raised a question on the Cygwin list as well, but thought this list would be appropriate too. The issue is that the CPU on the sending side is fully allocated by rsync/ssh (both taking 50%) during a file transfer. This is the command I use: rsync -e ssh * <user>@<server>:/data

Hello, How to add x values in graph points? Thanks a lot, Romildo x <- c(22.44, 20.14, 15.85, 15.97) plot(x, type="n", axes=FALSE, ann=FALSE, labels=c(22.44, 20.14, 15.85, 15.97)) par(lwd=1) lines(x) points(x, pch=5, bg="grey", cex=1.5) axis(2, las=1) axis(1, at=1:4, lab=c("none", "50-50", "80-20", "90-10")) box()

Add generic virtualization support for pinning the current vcpu to a specified physical cpu. As this operation isn't performance critical (a very limited set of operations like BIOS calls and SMIs is expected to need this) just add a hypervisor specific indirection. Such a pinning should last as short as possible as it might block sensible vcpu scheduling and maybe other hypervisor functions

Hi, Keir, In debugging the issue "system hang when doing cpu offline", I identified a situation that could cause a dead lock. The scenario is: mwait_idle_with_hint inside play_dead will access per cpu variable, which causes #PF. The #PF handler will use printk, which will schedule a tasklet. In scheduling a tasklet, per cpu variables are needed, otherwise, there will be another #PF.

Hi everybody, Using libvirt 1.0.0 how does one change the L2 cache size of the virtual CPU? I can change the CPU model but the cache size never changes: <cpu mode='host-passthrough'/> <model>Nehalem</model> OR <cpu match='exact' mode='custom'/> <model>Nehalem</model> Is there a qemu requirement? -- peter matulis

Hi everybody, I'm using the PHP API to make a web interface interact with the virtual machines installed on some hypervisor. Everything is fine, but I would like to find a way to get the guest's cpu and mem usage, so that it should be possible to make some rrd graphs. I didn't find out anything and also it seems looking around that there is no way to obtain those data. What is strange

> OK, here is a patch which provides fine grained cpu utilization > reporting. Some notes: I really can''t see the point of this patch -- it isn''t necessary to log every scheduling operation to record CPU usage for a domain over multiple time scales. Simply exporting the cumulative CPU usage for all domains and polling it from dom0 will enable you to do this. If you do

On many Online reference on xen,they are mentioning about assigning vm to physical CPU core rather than setting the affinity to "*any cpu*". Can there be any performance improvement if we do in this way. Will this make Credit scheduler to limit to few choices and results in poor scheduling. If it really improves performance then how to do this if we have 4 cores and 8 vms to run.With

Hello everybody, Thank you Fufu Fang for your quick reply: With tinc version 1.0.35 and the bellow options at 100% CPu load i get about 10 MB/s... PMTU = 1400 PMTUDiscovery = yes #Cipher = none Cipher = chacha20-poly1305 Digest = blake2b512 Tried Cipher = none as well and also got 10MB/s with 100% CPU on one thread the other three available threads are idle. With inc_1.1~pre17-1.1_amd64.deb

Hi, Keir, Thanks for checking in cpu online/offline support. Another thought inspired by Kevin, due to the time sequence that different cpus enter the stop machine context, there is a small window that some kind of softirqs (say softirq_A) are issued to the dying cpu right after the dying cpu has already handled softirq_A in do_softirq before entering stop_machine softirq. So this softirq_A

xen_play_dead calls cpu_bringup() which looks weird, because xen_play_dead() is invoked in the cpu down path, whereas cpu_bringup() (as the name suggests) is useful in the cpu bringup path. Getting rid of xen_play_dead()'s dependency on cpu_bringup() helps in hooking on to the generic SMP booting framework. Also remove the extra call to preempt_enable() added by commit 41bd956 (xen/smp: Fix

Hello everybody. I would like to ask a question. Does anybody here know how to use ardj with ezstream? I have been trying to find some documentation on how to get it set up and working properly. But, I cannot find any. So, I hope that one of you knows how to use the software in conjunction with each other, because I would like to set up an intelligent scheduler that includes, jingles, and other

I would like to know how much memory and cpu virtual machine are using so yes guest's perspective. I'm building a web app that has to alert the user when the vm is going to be stressed and I would like to do this in terms of mem and cpu usage.
