[libvirt] [RFC 5/5]: Rewrite findLuns function
by Chris Lalancette 12 Jun '08

12 Jun '08

This rather large patch rewrites the virStorageBackendISCSIFindLUNs() function to only rely on sysfs for finding LUNs, given a session number. Along the way, it also fixes the bug where we wouldn't find LUNs for older kernels (with the block:sda format), and also (possibly) fixes a race condition where we could try to find the LUN before udev has finished connecting it. I say it "possibly" fixes it because I haven't been able to hit it so far, but I definitely need more testing to try and confirm. Signed-off-by: Chris Lalancette <clalance(a)redhat.com>

[libvirt] [RFC 4/5]: Move the sendtarget command into the login command
by Chris Lalancette 12 Jun '08

12 Jun '08

A small bugfix; we only need to call the iscsiadm sendtarget command when we are first logging in; we don't need to do it for logout. Move the sendtarget command into the Login() function. Signed-off-by: Chris Lalancette <clalance(a)redhat.com>

[libvirt] [RFC 3/5]: Fix up the call to iscsiadm --mode session
by Chris Lalancette 12 Jun '08

12 Jun '08

Older versions of iscsiadm didn't support the "-P 0" flag to the "iscsiadm --mode session" command. However, just running "iscsiadm --mode session" seems to work on all version of iscsiadm commands back to FC-6, so just use that. Signed-off-by: Chris Lalancette <clalance(a)redhat.com>

[libvirt] [RFC 2/5]: Cleanup carriage returns in util.c
by Chris Lalancette 12 Jun '08

12 Jun '08

In src/util.c, virLog is just a wrapper around fprintf(stderr). Make sure to put line breaks at the end of lines that use virLog() (noticed during testing). Signed-off-by: Chris Lalancette <clalance(a)redhat.com>

[libvirt] [RFC 1/5]: Return exitstatus from virStorageBackendRunProgRegex
by Chris Lalancette 12 Jun '08

12 Jun '08

This patch changes things around so that virStorageBackendRunProgRegex() does *not* virStorageReportError() if the fork()/exec() process it spawned returned a != 0 exit code. Rather, it returns the exitcode in this case, and it is up to the higher level to determine whether this is a fatal error or not. The use case for this change is in the iSCSI stuff; older versions of iscsiadm tools would return a failure when getting the session number, despite the command succeeding.

[libvirt] [RFC 0/5]: Fix up iSCSI handling (again)
by Chris Lalancette 12 Jun '08

12 Jun '08

All, I've been sitting on this for way too long, so I'm sending these patches out for some initial review while I continue to test them. The following 5 patches rework the iSCSI LUN scanning again. The aim here is to: 1) Do minor cleanup of the existing code 2) Fix a bug where we aren't properly finding the LUNs on pre 2.6.24 kernels 3) Fix a bug seen in oVirt where we race between libvirtd scanning the sysfs path and udev actually making the sysfs path in the first place 4) Further lessen our dependence on direct calls to iscsiadm, in case they change the output in the future. I've started testing this patchset against a variety of Fedora's, old and new. Anything older than FC-6 is a lost cause; either it doesn't have iSCSI stuff (FC-1 through FC-4), or the iscsi stuff it has is so radically different that it's basically a different commandset (RHEL-4 and FC-5). In some light testing, though, this patchset seems to work on FC-6, F-7, F-8, and F-9 (RHEL-5 still to be tested). As Dan mentioned earlier, I have collected output from the relevant iscsiadm commands so that we can build our own fake iscsiadm in tests; I'll be working on that test as well as continuing to test these patches against live iSCSI targets. Note that this patchset is not to be applied yet; I've only lightly tested it so far. I'd just like to see what people think about all of this. Chris Lalancette

[libvirt] qemudDomainSetMemory() / qemudDomainSetVcpus() error codes
by Kaitlin Rupert 11 Jun '08

11 Jun '08

Hello, I noticed qemudDomainSetMemory() / qemudDomainSetVcpus() use the VIR_ERR_INTERNAL_ERROR error code when the caller attempts to set the mem/vcpus of an active domain. In this case, returning something like VIR_ERR_NO_SUPPORT would indicate that this is an invalid call - which would distinguish the error from a failure that occurred during the call. Is it possible to use such a return code to indicate what is supported by QEMU/KVM and what isn't? Thanks! -- Kaitlin Rupert IBM Linux Technology Center kaitlin(a)linux.vnet.ibm.com

[libvirt] Release?
by Richard W.M. Jones 10 Jun '08

10 Jun '08

I've just had a chat with Daniel about whether it's time for a new release of libvirt. My own primary focus is getting the virDomain*Peek APIs into a released version so I can use them from Fedora. libvirt 0.4.2 was released on 8th Apr 2008. I just scanned the changelog and there's a pretty long list of new features: - Support for serial and parallel devices in Xend - Network interface model in QEMU network devs - SetVcpus, DomainGetMaxVcpus, VCPU pinning in QEMU - Disk "bus"es - Support for Xenner - Deprecate conn/dom/net fields in virterror - HTML documentation completely restructured - MinGW fixes - Memory leaks plugged - Added HACKING file and lots of work on unifying syntax and methods used in the code base to a single standard - Lots of LXR changes - virDomain*Peek APIs - and of course many bug fixes So is it time for a release?

[libvirt] [PATCH] Fix UUIDString for python bindings
by Cole Robinson 10 Jun '08

10 Jun '08

The attached patch fixes a few issues in the python bindings. First, UUIDString has, to my understanding, never worked. It expected to be passed a buffer to fill with the uuid, which through my tests isn't realistically doable from python. I added custom bindings to fix this, and it now works as expected, taking no arguments and returning a string. UUID for a storage pool wasn't being generated with its custom function, so it too was broken. This is also fixed. I also removed some stale entries for virStorageVol UUID functions from generator.py which were probably just carried along from an old version of the storage api patches (storage volumes don't use UUID).

10 Jun '08

This patch implements virDomainMemoryPeek, which allows callers to peek into guest (virtual) memory. Currently the patch contains a QEMU driver and remote support. There's also a big comment in the source describing how to do Xen. Obviously the use case for this is virt-mem: http://et.redhat.com/~rjones/virt-mem/ Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones Read my OCaml programming blog: http://camltastic.blogspot.com/ Fedora now supports 59 OCaml packages (the OPEN alternative to F#) http://cocan.org/getting_started_with_ocaml_on_red_hat_and_fedora

[libvirt] [PATCH] lxc: new tty for container
by Dave Leskovec 09 Jun '08

09 Jun '08

The lxc driver xml parser treats the console element as input when it should be output only. This obviously causes problems when anything other than /dev/ptmx is specified or when a container is shutdown and then restarted without redefining it (so that the console field is reset). This patch treats the console element as output only and always creates a new device when starting a container. Also fixed up a string overflow when storing the device name. Thanks! -- Best Regards, Dave Leskovec IBM Linux Technology Center Open Virtualization

[Libvir] Reopening the old discussion about virDomainBlockPeek
by Richard W.M. Jones 09 Jun '08

09 Jun '08

Virt-df[1] has now gained the ability to fully parse LVM2 partitions, thus: # virt-df -c qemu:///system -h Filesystem Size Used Available Type rhel51x32kvm:hda1 96.8 MiB 14.6 MiB 82.2 MiB Linux ext2/3 rhel51x32kvm:VolGroup00/LogVol00 6.4 GiB 3.6 GiB 2.8 GiB Linux ext2/3 rhel51x32kvm:VolGroup00/LogVol01 992.0 MiB Linux swap However it still has to do it by opening the local partitions / files, which means it isn't using a "proper" part of libvirt and more importantly it cannot run remotely. I'd like to find out whether the time has come for us to look again at a virDomainBlockPeek call for libvirt. Here is the original thread plus patch from 7 months ago: http://www.redhat.com/archives/libvir-list/2007-October/thread.html#00089 (I've attached an updated patch against current CVS). I appreciate that some cases might not be simple (iSCSI?), but the same argument applies to block device statistics too, and we make those available where possible. I think a best-effort call allowing callers to peek into the block devices of guests would be very useful. Rich.

[libvirt] Routing
by Dave Walker 09 Jun '08

09 Jun '08

Hi, I'm trying to set up routed networking using libvirt0.4.2, but not having much joy, I cannot ping from either the host OS, or elsewhere on the network (or inverse from the guest OS). I would really appreciate some assistance as I haven't been able to find many routing examples. I'm using the example provided[0], which does create virbr1. If I can provide any further information, please let me know. $ ifconfig = http://pastebin.com/f69bf71bf $ route = http://pastebin.com/f69c73b03 $ cat /etc/libvirt/qemu/networks/default.xml = http://pastebin.com/f3fee05fb $ cat /etc/libvirt/qemu/ubuntu.xml = http://pastebin.com/f477c53a6 [0] http://libvirt.org/formatnetwork.html#examplesRoute Kind Regards, Dave Walker

[libvirt] PATCH: Fix check for inactive network
by Daniel P. Berrange 09 Jun '08

09 Jun '08

When building up the QEMU command line args we forgot to check for a NULL when creating the TAP device arg. This can happen if the network being connected to the VM is not running. This is something I broke in the refactoring of the ARGV construction in the QEMU driver. Dan.

[libvirt] Workshop Virtualization Technologies in Essen, Germany
by Henning Sprang 04 Jun '08

04 Jun '08

Hello everybody! For the third time, I arranged a "Workshop on Virtualization Technologies" in cooperation with the Linuxhotel in Essen, Germany. Our goal is, to provide developers of Open Source Software related to virtualization, and interested, skilled administrators with the possibility to come together for a weekend to work on their projects, exchange experiences and play around with the technology. The Linuxhotel as a location delivers a great, relaxed athmosphere and a perfect infrastructure to enable carefree working. Details - currently in German only - here: https://wiki.villa-vogelsang.de/doku.php?id=virtualisierung:start It's no problems to attend the workshop if you're not speaking german - please let me know if you're interested, and I'll give you more info on the details - basically it is, if you are an OpenSource developer in a virtualization related field, you can attend for free, otherwise you have to pay a flat fee of 135 Euros. We're looking for sponsors to see if we can get to reimburse travel costs for the Open Source developers. I'd be glad to see you there! Registration will be by first come-first serve principle - the event will be limited to 20 Persons. Henning Sprang -- Henning Sprang http://www.sprang.de | http://lazyb0y.blogspot.com/

[libvirt] remote access libvirtd / bindings for php/asp
by Stefan de Konink 04 Jun '08

04 Jun '08

Hi, A few people around me want to use php or asp to access libvirtd. Along this wish is to access it as 'proxy' for the entire cluster (this is where I come in). My target it to make a proxy for libvirtd that allows all host in the network to be managed by any libvirtd instance that has the sufficient certificate. Now it seems clear that this dispatch/proxy functions are doable. But what I wonder about is the actual access to libvirtd. There seems to be a pretty big warning about the XDR/ RPC calls. My people would like to see bindings to connect to libvirtd by php or asp/.net, is there any progress on that one? Stefan
