similar to: no callback on VIR_DOMAIN_EVENT_ID_BALLOON_CHANGE in 0.10.2

Hi , I Sent this to the wrong list (libvirt-devel) on friday ... so i am trying to send it to the correct one this time. Apologize for double posting. I also created a ticket on bugzilla.redhat.com for this https://bugzilla.redhat.com/show_bug.cgi?id=927336 still i am posting it here because is absolutely possible i am doing something wrong and someone here will see it . Description of the

Eric, thank you for your response. Virsh memtune, setmaxmem and setmem won't survive a reboot. I'm hoping to find  a solution that can survive reboot.   On Thursday, January 30, 2014 11:36 AM, Eric Blake <eblake@redhat.com> wrote: On 01/30/2014 10:11 AM, mallu mallu wrote: > I'm trying to permanently change memory allocation for a libvirt-lxc domain.

Hi I have just started to investigate the possibilities of resizing memory for my kvm virtual machines on the fly. It works just fine with virsh setmem and that's great. Now, what I'm wondering about is the <memory> directive in the xml domain definition. Why would I not just set that to the size of available RAM in the host machine? Am I missing some nuance or finesse to the

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

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/solutions/2017943 Now we use following

I'm trying to permanently change memory allocation for a libvirt-lxc domain. So far I tried changing memory in memory.limit_in_bytes under /cgroup/memory/libvirt/lxc/<container>/.  This didn't help. It appears that libvirt is not reading changes in cgroup. My requirements are 1) Be able to dynamically change memory of a LXC domain without reboot 2) The memory change must survive

How can I disable libvirtd from attempting to suspend VMs on poweroff / reboot? It is slowly filling up our /var/ filesystem with save points at /var/lib/libvirt/qemu/save/<vm name>.save, even though I'm not initiating any suspend or restore functionality. I checked /etc/libvirt/libvirtd.conf and /etc/libvirt/qemu.conf but could not find anything. This is CentOS 5 with libvirt

Is there a way to automatically set the permissions of cgroups directories created by libvirt when a VM is launched? Although it looks like I can set permissions on top-level /cgroup directories via cgconfig.conf, the cgconfig.conf manpage says "Permissions are related only to enclosing control group and are not inherited by subgroups.". From this, I believe that when libvirt

Hi, i have a Linux domain (Ubuntu 14.04) where we like to be able to change the amount of usable memory. We have a balloon device and statistics are switched in 5 sec. rhythm. The domain shows very quickly changes (following top) when we change the memory size with setmem, but the host does not show changes in the use of memory for the respective domain. Is that expected behavior ? Host is SLES

[please don't top-post on technical lists; also, it would be nice if you could convince your mailer to wrap long lines) > Eric, thank you for your response. Virsh memtune, setmaxmem and setmem won't survive a reboot. Ah, but they DO survive reboots, if you use the right options.  'virsh memtune --live --config' affects both the running guest and the next boot. -------

As planned and after most of the clang detected problems got fixed (thanks Eric !) the new release is available at: ftp://libvirt.org/libvirt/ It's a mixed release, it includes a number of improvements as well as many bug fixes and a few new features: Features: - support various persistent domain updates (KAMEZAWA Hiroyuki) - improvements on memory APIs (Taku Izumi) - Add

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"? ?

As scheduled, libvirt 0.9.0 was tagged and pushed today, it's available from FTP at: ftp://libvirt.org/libvirt/ This is a large release w.r.t. the amount of features and changes, and well worth bumping the middle version number. We are also getting closer to a 1.0.0 release ! Features: - Support cputune cpu usage tuning (Osier Yang and Nikunj A. Dadhania) - Add public APIs for storage

I'm running libvirt 0.10.2 and qemu-kvm-1.2.0, both compiled from source, on CentOS 6.
