Hi, the function libxl_domain_setmaxmem in libxl.c doesn''t seem to do anything besides argument checking, or am I overlooking something? Cheers, Markus _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

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 fo...

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

Hello, Does KVM support hotadd memory and hot-plug cpu? I checked it using the virsh command but I can only increase the memory to the maximum memory that is initially set But setmaxmem command is failing. Which means this require a reboot of the guest # virsh setmaxmem 4 1048576 error: Unable to change MaxMemorySize error: Requested operation is not valid: cannot resize the maximum memory on an active domain #virsh setvcpus 4 4 error: internal error: unable to execute QEMU comm...

Hi All, I am new to libvirt, i wander how we can achieve below objective, i read through a lot from libvirt.org but couldn't found any thing solid something equivalent to this:- virsh dumpxml dom > /tmp/dom.xml $EDITOR /tmp/dom.xml && virsh define /tmp/dom.xml What i try to achieve is to have one management server that install with libvirt in place then we can use libvirt

Changing things directly in cgroups goes behind libvirt's back, while changing it through the libvirt API allows you to hot-plug the changes as well as control whether the next boot will have the same new limits. -- Eric Blake eblake redh...

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. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

Hello, After I limited max memory usage in one domain, how could I reset mem-max to no-limit? Besides, I used "xm create -F xxxx.xm" to create a domain successfully. But when I shut it down, this domain disappear from "xm list". Why that happened? Thanks. Vincent
