Better error codes when stopping a VM that is already stopped
Hi, Sometimes when stopping a virtual domain using virDomainDestroy(), I come across a domain that is already stopped. (For example when someone already stopped the domain manually using virsh or because the guest OS issued a shutdown.) This is a special case that I absolutely need to catch and handle. Unfortunately, when this happens, and I call virGetLastError() afterwards, I always just

Exim and Dovecot2 SASL: 435 Unable to authenticate at present
Hi. I had working Exim 4.71 and Dovecot 1.2.9 SASL configuration on Ubuntu Lucid, but needed some features from dovecot2, so I installed 2.0.13 from https://launchpad.net/~carsten-uppenbrink-net/+archive/dovecot2 . Now I get Subj error while trying to authenticate via dovecot auth-client socket. However IMAP auth works fine with 2.0.13 and smtp auth worked fine until upgrade, so I think

How to tell if a hypervisor connection has died?
Hi, What's the best way to tell if a virConnect object is not good to use anymore? (For example because the libvirtd on the other side crashed/has been stopped or because of some network failure) When I try this, the first API call I do on a broken connection yields an error with error number 38 (VIR_ERR_SYSTEM_ERROR) and all subsequent calls yield an error number 1

Qemu driver not supporting VIR_DOMAIN_DEVICE_MODIFY_CONFIG yet?
Hi, According to the docs on http://libvirt.org/html/libvirt-libvirt.html#virDomainDetachDeviceFlags I ought to be able to do virDomainDetachDeviceFlags( <domain>, <devicexml>, VIR_DOMAIN_DEVICE_MODIFY_LIVE | VIR_DOMAIN_DEVICE_MODIFY_CONFIG); to detach a volume both from a currently running VM instance and permanently from the defined config file. If I actually try that,

Multiple Signatures on SSH-Hostkeys
Hello, OpenSSH-wizards. In our company, we have looked into SSH-HostKey-signing in order to realize automated access without the need to accept the server's hostkey, manually. I got it to work with the HostCertificate-directive inside the sshd_config. Now, I was wondering whether it is possible to have multiple signatures, so I can, for example, sign the hostkey once with a

NWFilter and IPv6
Hi, Libvirt's nwfilter ships a number of useful filter scripts by default, but none to handle IPv6 traffic. Is there a particular reason for that, or is that just because nobody has got around to that yet? One interesting thing about dealing with IPv6 traffic is that hosts often have several auto-configured addresses, usually at least one auto-configured link- local address under

Bug? virGetLastError() returns NULL after virDomainCreate() if Domain running already
Hi, As the subject line indicates, when I'm calling virDomainCreate() to start a defined domain, and that command fails because the domain is already running at that point, virGetLastError() will return NULL, instead of a proper pointer to an error code. Libvirt will, however, print an error to the console: libvir: QEMU error : Requested operation is not valid: domain is already running

Migrating fails with "Timed out during operation: cannot acquire state change lock"
Hi, After recently upgrading to 0.9.11 (as shipped with Fedora 17), I was just trying to migrate a qemu domain from one host to another (using virDomainMigrateToURI()), when I got this error message: Unsafe migration: Migration may lead to data corruption if disks use cache != none Okay, this is explainable (if a bit disappointing - I would have hoped that qemu would be able to disable disk

SSL Ports
I have ice cast up on my server, ssl is working as intended and I have both a standard feed and ssl port working. Only big issue I have is even though the SSL port is set for 443 it is also running on Port 80. Is there some reason port 80 is running alongside 80 and is there a way to run it without Port 80 being used?

Getting CPU and memory usage statistics for the host
Hi, I have noticed that virt-manager has the ability to show me the current cpu- and memory-usage of both the host and running guest machines. How does it do that? I could make good use of that information myself in the client applications I'm writing, however, from what I can see on http://libvirt.org/html/libvirt-libvirt.html, I have no idea how to go about getting it from libvirt.

Reg: Difference between chroot & pivot_root
Hi, What is the difference between chroot & pivot_root. They don't seem obvious based on the man pages apart from the below mentioned caveats. 1) Inherited Open file descriptors, have to be explicitly closed. 2) Does not change CWD of the process, which can be overcome by doing a chdir before & after chroot call. Any information on this would be useful. Thanks,

How to install libvirt 0.9.4 RPM on Fedora 14?
Hi, I'm trying to install the newest version of libvirt and libvirt-client from the rpms at ftp://libvirt.org/libvirt/ on a Fedora 14 machine. The naming of the rpms as "libvirt-0.9.4-1.fc14.x86_64.rpm" suggests that this is exactly the system this was made for, however, installation still does not go smoothly. When I try to install these packages with yum install

Interpreting NB GLM output - effect sizes?
Hi, I am trying to find out how to interpret the summary output from a neg bin GLM? I have 3 significant variables and I can see whether they have a positive or negative effect, but I can't work out how to calculate the magnitude of the effect on the mean of the dependent variable. I used a log link function so I think I might have to use the antilogs of the coefficients but I have no idea

Shouldn't vol-upload / virStorageVolUpload() be doing some format conversion?
Hi, I just tried using vol-update to copy an image file to a storage pool, and I noticed that, at least in my configuration (qemu backend, storage pool of type "dir"), this command does not appear to be doing any kind of format conversion. It simply copied the source file as-is over the file in which the target volume was stored with no checks whether that even makes sense. The

libvirt does not recognize all devices in iscsi and mpath pools in a predictable manner
Hi, I'm using libvirt 0.8.3 on Fedora 14 (as I wrote earlier, I'm having some trouble updating to the newest version), and I'm having problems getting iscsi and mpath storage pools to work in a usable and consistent manner. I have two storage pools defined on the host machine, one for raw iscsi- devices and one for those same iscsi devices device-mapped by multipath. They look

VM parameters best practice?
Hi, When creating many virtual machines from a template (disk image), you often need to set some different parameters for each vm. Those usually include root passwords and/or ssh public keys for login, ssh Host keys (so that a) not all the VMs have the same host key and b) the user can know the real host key for his vm before connecting for the first time) plus any number of user-defined

Working example of logical storage pool and volume creation?
Hi all, Does anyone have a working example of creation of a logical storage pool and volume? I'm hitting a wall getting logical volumes to work on RHEL 6 beta. There's a single drive I'm trying to setup (sdc) as a libvirt managed logical storage pool, but all volume creation on it fails. Here's what I'm finding so far: Prior to any storage pool work, only the host
