How to measure memory utilizatin of guest when dommemstat reports "RSS" is more than "ACTUAL"? Following is the output on RHEL 6.6 # dommemstat 1 actual 16777216 rss 16890372 # dommemstat 2 actual 16777216 rss 16460516 I found following article on Redhat which suggests that this is normal/expected? https://access.redhat.com/...

Gleb, you didn't mention what language (binding) you're using. In virsh, use the "--period N" option for the dommemstat command at least once in order to enable stats collection. -- Claudio

...in C and Python, I'm not seeing VIR_DOMAIN_EVENT_ID_BALLOON_CHANGE ever tick, although I do see other events like VIR_DOMAIN_EVENT_ID_LIFECYCLE, VIR_DOMAIN_EVENT_ID_REBOOT, and VIR_DOMAIN_EVENT_ID_RTC_CHANGE. The balloon is definitely changing, and is reflected by both virsh -c qemu:///system dommemstat <dom> and free inside the guest. Here's the balloon in my config for reference: <memballoon model='virtio'> <alias name='balloon0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function=...

Hi All Is there a tool to monitor qemu-kvm guest vm memory usage ( free in guest vm)?Nowadays, I have already researched some methods:1. qemu-kvm process memory usage.? ? ?Since qemu-kvm process memory usage always increases as time goes on, it will not reflect the memory usage in vm.2.?virsh dommemstat? ? ?Just as method 1.3.?virsh qemu-monitor-command --hmp [domain name] "info mem"? ? ?(1) when guest vm memory size less than 4Gbytes, it will output something like this:? ? ? ? ? ? 7f882000-7f883000 00001000 urw????????????7fbf8000-7fbf9000 00001000 urw????????????88000000-88001000 00001...

Hi everybody, I'm using libvirt java api bindings for my thesis. I would like to know if there is a way to obtain live information about cpu and mem usage of a domain. Regards, Enrico De Maio Skype: enrico.de.maio Mobile: +39 338 205 3397

...n on a VM to which 8GB of MaxMemory or more are allocated then the information reported with virsh dominfo , virsh dumpxml after the balloon change has been performed are wrong. The actual balloon is inflated correctly though and that is verifiable both in the vm itself and through the "virsh dommemstat" commands. Platform is Centos 6.4 (problem was present in 6.3 as well starting with libvirt-0.9.10-21.el6.3.7 ) The patch that actually is causing the problem is patch number 398 in the src rpm for libvirt-0.9.10-21.el6.3.7 : libvirt-Wire-up-handling-for-QMP-s-BALLOON_EVENT.patch ( https:/...

...timeout is 30s. It seems that the remoteDispatchDomainMemoryStats job is too slow to let the stop job wait timeout. Then I tried to reproduce this process. The step is as follows: First step: add a sleep on ‘qemuProcessEventHandler' by using pthread_cond_timedwait. So can execute 'virsh dommemstat active’ command at this time interval. Second step: start a vm to test Third step: execute 'virsh shutdown active’ to shutdown the vm Fourth step: execute 'virsh dommemstat active’ when stop job is sleep. Then it works. The test vm state became to 'in shutdown’, and the libvirt log is...

...; The domain is not at 100% memory capacity. How can I diagnose this further? You're asking the wrong interface. dominfo only tells you how much of the memory balloon is in use (here, none), and does not ask how much memory the guest claims to be using. 'virsh memtune' and 'virsh dommemstat' ask different questions, and may be able to give you more insight into the guest's current memory usage (but it might also be something you can't learn without guest cooperation). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

I have sent a similar email about this problem. But I did not describe carefully, so I would like to explain it in more details. I am using 'virsh setmem' to ajust vm memory online. However, I don't know what is the lowerlimit that can be set to. And I try to use 'virsh dommemstat' to get 'unused' memory so that I can calculate the lowerlimit memory with this value, but it doesn't work when it comes to windows systems as I cannot set vm memory down to 'available - unused' in windows system. I suppose it's caches memory that causes this problem, so...

Hello, A collecting period should be set to get domain memory stats (virDomainSetMemoryStatsPeriod function or virsh dommemstat --period from command line). Is there a way to set this period automatically using XML config or any other way?

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

Hi folks, is it possible to monitor and gather statistics in realtime (CPU, memory, HDD, network, ... - something like dstat) of guest systems with libvirt through console from host system (KVM based)? If yes, do those guests need to be created through libvirt? Thanks for your help and time.
