[libvirt] [PATCH] storage: fix disregarding specified owner/group permissions
by Ryota Ozaki 11 Mar '09

11 Mar '09

Hi, storage_conf.c always sets owner/group permissions as 0, even if non-0 values are specified in XML. Because XPaths in DefParsePerms functions are wrong and XPath functions using the XPaths fail, as a result the values obtained by getpid()/getgid() are used instead. This patch fixes this and also unifies duplicated functions, virStoragePoolDefParsePerms and virStorageVolDefParsePerms, as a common function virStorageDefParsePerms to fix the bug prettily. One concern I have is the default value of mode permission in virStorageDefParsePerms is now 0700 but that in virStorageVolDefParsePerms was 0600. Is this considerable change? Thanks, ozaki-r

[libvirt] PATCH: Fix hang setting QEMU vcpu count
by Daniel P. Berrange 10 Mar '09

10 Mar '09

In the QEMu driver, the qemudDomainSetVcpus() entry point is calling into another entry point qemudDomainGetMaxVcpus(), this causes a deadlock due to recursive mutex locking. The qemudDomainSetVcpus() method should in fact be calling the internal method qemudGetMaxVCPUs(). This patch makes it do that, thus avoiding the recursive mutex locking.

[libvirt] some questions about libvirt features and limitations
by Florian Vichot 10 Mar '09

10 Mar '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everyone, I'm working on a open source project (http://www.hynesim.org) in which we needed libvirt-like functionalities. As at the time, libvirt did not support OpenVZ, and it did not support VirtualBox, we went and implemented our own wrappers around Kvm/Qemu, VirtualBox and OpenVz (Honeyd too, but our wrapper is such an ugly hack that it doesn't really deserve mention). Now that time has passed, we'd would like to stop duplicating efforts, and use libvirt instead, and concentrate on more innovating functionalities for Hynesim. Also our wrappers are terrible hacks, and do a lot less error checking than libvirt :) But before I can replace our wrappers with libvirt, we're missing some functionalities (that I will propose a patch for if required), and there are a few questions concerning libvirt I've not managed to find an answer for, so I'd be very grateful if I could get some advice on them. Here goes: ------- Is it possible to add a device for any type of domain that would correspond to a TAP device on the host, and would be seen as a regular ethernet interface with a specific MAC address in the virtualized domain ? The "raw" commands to achieve that in OpenVZ and Qemu, for example, are: # kvm ... -net nic,macaddr=00:11:22:33:44:55 -net tap,ifname=tap0,script=no # vzctl set 100 --netif_add eth0,00:11:22:33:44:55,tap0 Is that doable in every driver supported by libvirt ? ------- Is the libvirtd daemon necessary for drivers other than Qemu ? I've been using the openvz driver alone for some tests (by connecting to "openvz:///system"), and yet I get warning messages: # sudo ./hellolibvirt openvz:///system Attempting to connect to hypervisor libvir: Remote error : unable to connect to '/var/run/libvirt/libvirt-sock': No such file or directory libvir: warning : Failed to find the network: Is the daemon running ? libvir: Remote error : unable to connect to '/var/run/libvirt/libvirt-sock': No such file or directory libvir: Remote error : unable to connect to '/var/run/libvirt/libvirt-sock': No such file or directory libvir: warning : Failed to find a node driver: Is the libvirtd daemon running ? Connected to hypervisor at "openvz:///system" Hypervisor: "OpenVZ" version: 3.0.22 There are 0 active and 1 inactive domains Inactive domains: 897 Disconnected from hypervisor The libvirtd daemon is indeed not running, as I don't see why it should be: I thought it was only useful for qemu guests. Am I right ? What is the role of the daemon exactly ? ------- Apparently the only way to start an OpenVZ domain is by specifying a template. Only problem is, when the VE is stopped, and undefined, all modifications are lost in the "private" file system of the VE (as it is deleted). The way we circumvented this in Hynesim is by specifying the - --private option to "vzctl create" instead of the --ostemplate one. That way one can specify a dir that will be used directly as the filesystem for the VE. I was thinking maybe adding something along the lines of: <filesystem type='directory'> <source name='/path/to/ve/filesystem' /> <target dir='/'/> </filesystem> would do the trick. It looks simple enough to implement, so should I ? ------- Is there support in libvirt of "cloning" (duplicating a VM disk /filesystem) ? ------- Someone mentioned a VirtualBox driver. I'm highly interested in this. How is it going ? I'd be more than happy to beta test if required. Will it work with both PUEL and OSE versions ? When will it be ready for inclusion in libvirt ? How will you handle RDP access, as from what I saw only VNC is supported in libvirt currently ? ------- And last but not least, what are "node devices" ? The two pages about it are blank in the documentation. Are they the host machine, or a device of the host machine ? ------- I think that's all. Thank you for reading all this, Florian -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkmtcBwACgkQgRp+dNkqn68FjQCcDhoy0YuhUM37iRc2cbyDdh1N hE8AoKSAhoZJ7cSQ8zWSXr9XiOytTuLK =LSi9 -----END PGP SIGNATURE-----

[libvirt] Error in virt-install
by Nuno Fernandes 10 Mar '09

10 Mar '09

Hi, I've just installed an centos 5.2 with all the updates 'till now. Next i've tried the following install script that worked fine: virt-install -n test -r 512 --vnc --file=/dev/VolGroup00/test-os -- location=ftp://mirrors/centos/5/os/i386 -x 'text' Next i've rebuild rpm of libvirt to libvirt-0.6.1 (using --with-rhel5-api). The rpm build fine and installed without any errors. Next i've retried the virt-install script but i get the following error: [root@localhost ~]# virt-install -n test -r 512 --vnc -- file=/dev/VolGroup00/test-os --location=ftp://mirrors/centos/5/os/i386

[libvirt] PATCH: 0/25: Full thread support for libvirt public API
by Daniel P. Berrange 10 Mar '09

10 Mar '09

This patch series is (mostly) aimed at providing full support for threads in the libvirt API. Specifically we remove the restriction that a single virConnectPtr is tied to a thread. Multiple threads can safely use the same object (provided one doesn't free it behind another's back :-P ) This is tested to compile on Linux + Win32 (MinGW), hopefully doesn't break Solaris, but I'll be testing that soon too. I've tortured the patches in various nasty ways are they're now stable enough to let loose and probably merge for wider testing. It'll probably be easier to just fix future problems in tree, rather than maintain this patchset longer. The full patchset is also available here http://berrange.fedorapeople.org/libvirt-threads-2009-01-13/ Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|

[libvirt] OCaml libvirt bindings 0.6.1.0 released
by Richard W.M. Jones 10 Mar '09

10 Mar '09

http://libvirt.org/ocaml/ Not a lot of change, since the bindings are pretty much stable now. The main change, and reason for this release, was that since CVE-2008-5086 the virDomainBlockPeek and virDomainMemoryPeek bindings now require a read/write libvirt connection. This broke mlvirsh and virt-df which were requesting a read-only connection. I have now changed this (thanks David Lutterkort for pointing out the problem). Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-top is 'top' for virtual machines. Tiny program with many powerful monitoring features, net stats, disk stats, logging, etc. http://et.redhat.com/~rjones/virt-top

[libvirt] [Patch] Fix detach tap device on Xen3.3.1
by Takahashi Tomohiro 10 Mar '09

10 Mar '09

Hi, I made the patch that corrected the following problem. It is that when I executed the "virsh detach-disk" command on Xen3.3.1, Libvirt could not detach tap device and output the following error message. # virsh detach-disk Fedora xvdd libvir: Xen Daemon error : POST operation failed: xend_post: error from xen daemon: (xend.err 'Device 51760 not connected') The cause of this problem is incompatible of Xen3.3.0 and Xen3.3.1. I think Xen specific was changed by the following patch. http://xenbits.xensource.com/xen-3.3-testing.hg?rev/e0e17216ba70 If you have any comments, please suggest me.
