Well I use the latest QEMU 2.0.0 I have the latest CentOS 6.5 installed on the guest and unfortunately I can't get more stats that I have. > Which OS are you using in your guests?...

Which OS are you using in your guests? Of course, you need to have the virtio balloon driver up and runnig in your guests. Claudio

You also have to have new enough qemu that reports stats without blocking (qemu 0.14 or newer added stat reporting via qom-get, since the...

Hello, I'm trying to get memory usage statistic inside a guest machine using virDomainMemoryStats function at libvirt. According to http://libvirt.org/html/libvirt-libvirt.html#virDomainMemoryStatTags the structure could have a lot of useful memory statistic but the amount of parameters depends on the hypervisor and the driver. However using KVM I'm able to get VIR_DOMAIN_MEMORY_STAT_AC...

Hello, I need to get how much memory is used by a guest system, in order to implement some monitoring function which tells me if the system is overstressed. I am currently using java apis and the binding which was suggested to me was Domain.memoryStats(); This is a binding to int virDomainMemoryStats (virDomainPtr<http://libvirt.org/html/libvirt-libvirt.html#virDomainPtr>dom, virDomainMemoryStatPtr<http://libvirt.org/html/libvirt-libvirt.html#virDomainMemoryStatPtr>stats, unsigned int nr_stats, unsigned int flags). Problem is tha...

...conn = libvirt.openReadOnly(None) if conn == None: print "Failed to open connection to the hypervisor" sys.exit(1) try: domIds = conn.listDomainsID() for id in domIds: dom0 = conn.lookupByID(id) try: print "memory stats: %s"% dom0.memoryStats().values() except: print 'Failed to find the memory data of this domain' sys.exit(1) except: print 'Failed to find the main domain' sys.exit(1) But this code 'dom0.memoryStats().values()' is returning empty list.I need to collect...

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

Hi all, I want to attach cdrom by libvirt.py .But can't find a func in libvirt.py can finish this work. Who can help me ? Regard -- Seven Ling E-mail: jiejie.ling at qq.com

Hello, I have a few vms running on a blade server and i want to log the actual RAM and CPU utilization by these vms. dom.info(), libvirt API call is not giving correct results. It is always showing the max allocated resources. I have tried using virt-top also but same problem persists. Is there any thing that i am missing. -- Jatin Kumar -------------- next part -------------- An HTML attachment
