[libvirt] [PATCH] Improve error reporting when libvirtd is not installed
by Daniel P. Berrange 06 Dec '11

06 Dec '11

From: "Daniel P. Berrange" <berrange(a)redhat.com> Currently if you try to connect to a local libvirtd when libvirtd is not in $PATH, you'll get an error error: internal error invalid use of command API This is because remoteFindDaemonPath() returns NULL, which causes us to pass NULL into virNetSocketConnectUNIX which in turn causes us to pass NULL into virCommandNewArgList.

[libvirt] [PATCH 0/5] Interface pools and passthrough mode
by Shradha Shah 06 Dec '11

06 Dec '11

Interface Pools and Passthrough mode: Current Method: The passthrough mode uses a macvtap a direct connection to connect each guest to the network. The physical interface to be used is picked from among those listed in <interface> sub elements of the <forward> element. The current specification for <forward> extends to allow 0 or more <interface> sub-elements: Example: <forward mode='passthrough' dev='eth10'/> <interface dev='eth10'/> <interface dev='eth12'/> <interface dev='eth18'/> <interface dev='eth20'/> </forward> However with an ethernet card with 64 VF's or more, the above method gets tedious on the system. On the other hand, just parameterizing a string (eth%d) is inadequate, eg, when there are multiple non-contiguous ranges. Proposed Method: The 5 patches provided along with this introductory e-mail i) Introduce a structure to store the state of all the virtual functions attached to each physical function ii) Find a free virtual function given the physical function. The forward specification will hence only mention the physical function as the interface sub element: Example: <forward mode='passthrough' dev='eth2'/> <interface dev='eth2'/> </forward> Shradha Shah (5): Moving the declaration of _pciDevice and _pciDeviceList to pci.h Added function pciSysfsFile to enable access to the PCI SYSFS files. Adding functions virNetDevGetVirtualFunctions and virNetDevGetNetName virNetDevGetVirtualFunctions: Gets the BDF of all the Virtual Functions given a physical function virNetDevGetNetName: Gets the interface name of the PCI Device. Addition of a new device structure to store the state of a Virtual Function Modifications to the Physical Device Structure to store state of its Virtual Functions If a system has 64 or more VF's, it is quite tedious to mention each VF in the interface pool. The following modification find a Free VF given a Physical Function when mode=passthrough. We also save the state of each VF. Hence modifications to networkAllocateActualDevice, networkNotifyActualDevice and networkReleaseActualDevice were required. The following patch does just that. src/conf/network_conf.c | 19 ++++- src/conf/network_conf.h | 10 ++ src/network/bridge_driver.c | 208 +++++++++++++++++++++++++++++++++++++------ src/util/pci.c | 52 ++++------- src/util/pci.h | 36 ++++++++ src/util/virnetdev.c | 89 ++++++++++++++++++ src/util/virnetdev.h | 10 ++ 7 files changed, 359 insertions(+), 65 deletions(-) -- 1.7.4.4

[libvirt] Group for accessing one/all VM graphics and not virsh
by Reeted 06 Dec '11

06 Dec '11

Hello libvirt people, is there a (preferably simple) way in Linux to allow a certain set of users to be able to do: virt-viewer --connect qemu+ssh://username@virthost/system vmname for connecting to virt-viewer BUT without letting them do all the other things that can be done with virsh? I know that if I add them to the libvirtd and kvm groups, they will be able to connect with virt-viewer to any virtual machine AND ALSO do any virsh command on any virtual machine. This is too much permission. I can accept the first part (a way to allow a group of user to connect with virt-viewer to all the virtual machines of the host) since more restriction can be enforced by using VNC passwords... But if they are also able to do anything in virsh that's too much. I am using only qemu and kvm in libvirt. Thank you R.

[libvirt] [PATCH v4] Implement DNS SRV record into the bridge driver
by Michal Novotny 05 Dec '11

05 Dec '11

Hi, this is the fourth version of my SRV record for DNSMasq patch rebased for the current codebase to the bridge driver and libvirt XML file to include support for the SRV records in the DNS. The syntax is based on DNSMasq man page and tests for both xml2xml and xml2argv were added as well. This is basically un-reviewed version 3 of this patch rebased to the current codebase with changed version information to 0.9.9 as it's supposed to go in 0.9.9 or later because of current 0.9.8 features freeze. Also, the second part of this patch is fixing the networkxml2argv test to pass both checks, i.e. both unit tests and also syntax check.

[libvirt] [PATCH 00/14] Add a virtlockd lock manager daemon
by Daniel P. Berrange 05 Dec '11

05 Dec '11

The lock manager infrastructure we recently added to QEMU only has two possible drivers at this time, 'nop' and 'sanlock'. The former does absolutely nothing, while the latter requires a 3rd party package installed and is a little heavy on disk I/O and storage requirements. This series adds a new daemon 'virtlockd' which is intended to be enabled by default on all hosts running 'libvirtd'. This daemon provides a service for disk locking based on the traditional fcntl() lock primitives. There is a new libvirt manager plugin which talks to this daemon over RPC. The reason for doing the locks in a separate process is that we want the locks to remain active, even if libvirtd crashes, or is restarted. The virtlockd daemon has this one single job so should be pretty reliable and selfcontained. This patch series really benefits from the new RPC APIs, requiring minimal code for the new daemon / client At this time, virtlockd does not lock the actual disk files, but instead creates a lockspace & leases under /var/lib/libvirt/lockd. The lockspace we use for disks is named org.libvirt.lockd.files, and lease names are based on a SHA256 checksum of the fully qualified disk name. eg /var/lib/libvirt/lockd/org.libvirt.lockd.files/adf94fc33a24da1abff7dd7374a9919bb51efee646da8c3ac464c10cd59750bd These leases are all zero-bytes long and no I/O is ever performed on them, only fcntl() is used. So there is material overhead. Whenever creating or deleting leases, we first acquire a lock on /var/lib/libvirt/lockd/org.libvirt.lockd.files/org.libvirt.lockd.index A non-root virtlockd will instead use $HOME/.libvirt/lockd By default we gain protection out of the box against - Starting two guests on the same host with the same disk image not marked with <shareable/> - libvirtd getting confused and forgetting a guest, allowing it to be started for a 2nd time If the admin mounts a shared filesytem (eg NFS) on /var/lib/libvirt/lockd then this protection is extended across all hosts sharing that mount volume. As part of this series, I also introduce support for systemd services for libvirtd and libvir-guests.
