Are there any recommendations as to how often a new connection should be made versus reused? Right now we create a new connection *every time* we hit libvirt for something. We can easily change this so that a single connection is made for a series of libvirt calls, or even so that a single connection is used for the lifetime of the running application. What are the issues to consider when making

I'm seeing this problem with both the virtio and e1000 driver with both linux and windows guests. About 5 - 10% of the VMs I launch have network problems. They seem to always get an IP from the DHCP server (dnsmasq), but afterwards either they can not make an outside network connection or they lose connectivity at a later time. Sometimes the connectivity comes back, sometimes it doesn't.

Hello, I'm receiving a lot of these since a couple of days ago: libvirtd: 16:30:10.960: error : qemudDispatchServer:1282 : Too many active clients (20), dropping connection I'm trying to figure out where all these active clients are coming from. I have a daemon running the interacts with libvirtd, but it only creates two long-lived connections (I'm very sure). What constitutes an

Hi, I have set up KVM on FC12. I was wondering if its possible to Display the VM using spice + libvirt? As in, if I can define my domain with graphics like: <graphics type='spice' port='-1' autoport='yes' listen='0.0.0.0'/> or <graphics type='spice' port='5903' '

Hi, I need a small help. I am working on a project where i have to monitor network activity of a VM running on KVM. I am interested in how much data is going into the VM and how much data is coming out of the VM. I checked on the net and found out virsh domifstat is the way to go about it. 1. But looks like these stats also include bytes related to control traffic for the VM. Is there a way to

Dear all, I am working on a virtualization project that involves setting up virtual appliances over cloud. to implement the same, which tool is required to 1) create virtual appliances 2) deploy virtual appliances 3) manage virtual appliances/virtual machines Could you please guide me with some pointers or resources to get started with the implementation. Thank you. Saravanan Sundaramoorthy

Before starting with Ovirt, i would like to discuss for the following queries, 1) Ovirt will support all OS ? 2) Can i integrate Ovirt with my java applications ? 3) I am looking for the open source tool that which i can integrate with my java applications and manage cloud infrasturcture. 4) Managing the coloud infrastructure such as create image, deploy the image to cloud host provider ? 5)

Hi, I'm having problems with libvirt crashing after a couple hours when a specific domain monitoring program is running. I have pasted below the following: 1. libvirt version 2. qemu-kvm version 3. OS version 4. Kernel version 5. libvirt status post-crash 6. libvirtd.log (info level dump around crash; too long to post everything so just the beginning and end. UTC) 7. custom.log (on what

Hi list, long(ish) time libvirt users, first time poster. Question: Is the default network (192.168.122.0/24, NAT) created by libvirt needed at all when guests are connected to the host's bridge device (and not the default network) I.e. when I have <interface type='bridge'> <source bridge='br0'/> <model type='virtio'/> </interface> in

Regardless of the filesystem (i''ve used reiserfs, xfs, ext3), whenever I mount a fresh DRBD partition I get some nasty kernel messages. This is under Debian Sarge, Xen kernel 2.6.11.12-xen0 (dom0) using DRBD v0.7.11 (pulled from Debian "testing"). This is what I did to create the partition. On both nodes I created a new LVM storage device and started DRBD: # lvcreate

DV suggested that we document some libvirt setups using shared storage. I'm not a fan of NFS, so I wrote some blog posts on how to use iSCSI in the context of libvirt + KVM. There is of course more than one way todo things, so I've outlined a couple of different options. One completely manual command line approach using tgtadm on the iSCSI server:

Hi, I am exploring the migration APIs and was curious to know if I can use them with LXC containers for live migration from one node to another. If not LXC, then can I use them with OpenVZ containers ? If yes, what would be the general steps involved. Thanks, Sagar -------------- next part -------------- An HTML attachment was scrubbed...

All test machines are CentOS 5.5 (RHEL subscriptions purchased). We've had NFS3 storage working fine and decided to try NFS4. We can mount an NFS4 share on our KVM host, but the SELinux file context on the mountpoint directory is magically changed from virt_image_t to nfs_t. Restorecon refuses to change it back. Adding the mount option context=system_u:object_r:virt_image_t on either server

Hi I keep getting libvirtError: Timed out during operation: cannot acquire state change lock errors - what does this mean exactly ? Using Ubuntu 64 bit 10.04 host and guest -- Kind regards Julian Robbins

I studying how to attach USB devices to a KVM guest virtual machine using libvirt. Using the "vendor" and "product" to specify the source device seems like a good option since the "bus" and "device" values can change as a device is removed and re-inserted. The question I have is what should I expect to happen if I plug in two identical USB devices - so they

remap_block_devices was modifying the global device list while remapping device names for libata guests (which includes RHEL 6). This caused a failure later when the renamed devices were not present in the original XML.
