Hi Guy, Anyone know how we can set up the vnc password during using virt-install command ? # virt-install \ --connect qemu:///system \ --name demo \ --ram 500 \ --disk path=/var/lib/libvirt/images/demo.img,size=5 \ --network network=default,model=virtio \ --vnc \ --cdrom /dev/cdrom

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

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, 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

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

This patch supports to fix lock holder preemption issue. For kernel users, we could use bool vcpu_is_preempted(int cpu) to detech if one vcpu is preempted or not. The default implementation is a macro defined by false. So compiler can wrap it out if arch dose not support such vcpu pteempted check.

An over-committed guest with more vCPUs than pCPUs has a heavy overload in osq_lock(). This is because vCPU A hold the osq lock and yield out, vCPU B wait per_cpu node->locked to be set. IOW, vCPU B wait vCPU A to run and unlock the osq lock. Kernel has an interface bool vcpu_is_preempted(int cpu) to see if a vCPU is currently running or not. So break the spin loops on true condition. test

An over-committed guest with more vCPUs than pCPUs has a heavy overload in the two spin_on_owner. This blames on the lock holder preemption issue. Kernel has an interface bool vcpu_is_preempted(int cpu) to see if a vCPU is currently running or not. So break the spin loops on true condition. test-case: perf record -a perf bench sched messaging -g 400 -p && perf report before patch:

proxy/anyterm needs to go to the node that has our vm on it, not vmnodes:anyterm. This patch also requires a change to the anyterm.js file that ships with anyterm. The change is at the top: - var url_prefix = proxy/; + var url_prefix = window.location.pathname + /proxy/; Not quite sure how we're going to manage that change though. --- conf/ovirt-server.conf | 3 ++- 1 files changed, 2

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

I'm trying to track balloon growth after issuing a setmem command to a KVM guest with libvirt 0.10.2 and qemu-kvm 0.12.1.2 on CentOS 6.3. libvirt 0.10.2 was built from tar today and appears to be working fine. The guest is running CentOS 6.3 as well. Using the provided test programs under examples/domain-events/ in C and Python, I'm not seeing VIR_DOMAIN_EVENT_ID_BALLOON_CHANGE ever

Updates the installer to handle the scenario in which the guest and admin networks are the same by using an alternative httpd conf. Verified to work (eg oVirt managed vms are bootable) on the oVirt appliance so far. --- conf/ovirt-server.conf | 88 -------------------- installer/bin/ovirt-installer | 11 +--

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

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
