[libvirt] [PATCH] conf: Skip MAC checks when using an auto-generated one during detach-device
by Kothapally Madhu Pavan 30 May '16

30 May '16

When we try to detach a network device without specifying the mac address, random mac address is generated. As the generated mac address will not be available in the running vm, detaching device will fail erroring out "error: operation failed: no device matching mac address xx:xx:xx:xx:xx:xx found". This patch allows to match DetachDeviec xml using PCI address when mac address is not specified.

[libvirt] Entering freeze fro libvirt-1.3.5
by Daniel Veillard 29 May '16

29 May '16

Due to travel etc... I forgot to push RC1 on Thursday and could not yesterday, but I just tagged rc1 in git and am pushing signed tarball and rpms to the usual place now: ftp://libvirt.org/libvirt/ I think I can try to push rc2 on Tuesday or Wednesday, and then I will try to push 1.3.5 on Friday (3rd then), sorry for the delay, please give it a try, thanks Daniel -- Daniel Veillard | Open Source and Standards, Red Hat veillard(a)redhat.com | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH rfc 0/1] storage: vzstorage storage pool
by Olga Krishtal 28 May '16

28 May '16

In-Reply-To: This is first draft, that supports vzstorage in storage pools.i Virtuozzo Storage is a fault-tolerant distributed storage system, optimized for virtualization workloads. Vzstorage pool supports the same volume formats as directory, nfs, etc. In terms of volume management - there is no difference between these pools. You can find more information here: https://openvz.org/Virtuozzo_Storage XML: <pool type='vz'> <name>vz7_pool</name> <uuid>b27a72b5-a92e-4e58-a172-a80ba73b30fe</uuid> <capacity unit='bytes'>0</capacity> <allocation unit='bytes'>0</allocation> <available unit='bytes'>0</available> <source> <host name='127.0.0.2'/> <device path='vz7-vzstorage'/> <dir path='/pool1'/> </source> <target> <path>/vz7-vzstorage</path> </target> </pool> To compile libvirt with vz pool support use key --with-storage-vz I need some help to resolve some problems: - how to detect that pool is alredy mounted. - when we show pool sources do we need to show folders that may reside on vzstorage - I am not quite sure that we need host name in xml. I will be glad to here your opinion.

[libvirt] [PATCH] maint: update to latest gnulib
by Eric Blake 28 May '16

28 May '16

Pulls in several portability fixes, including the fact that gnulib now only works on platforms with two's complement signed integers. Also makes for a smaller delta on the next update (we are waiting on a license change to unsetenv for the sake of mingw). * .gnulib: Update to latest. * bootstrap: Resync from upstream. * tests/virstringtest.c: Drop use of obsolete probes of integer properties. Signed-off-by: Eric Blake <eblake(a)redhat.com> --- I'd like to get this in now, before RC1 is cut, so that we maximize the testing of the bulk of the gnulib changes (rather than waiting for the unsetenv change needed for mingw to land, but forcing the gnulib update to only get testing in RC2). * .gnulib 6cc32c6...8d807a9 (127): > gendocs.sh: Set default TOP_NODE_UP_URL in HTML output. >

[libvirt] inconsistency in attribute usage between hv drivers
by Laine Stump 28 May '16

28 May '16

I just came across this problem while looking for the proper place to put <ip> info for the host side of <interface type='ethernet'>. I don't think there's really anything that can be done about it now, since everything below has been in place for so long, but maybe it can serve as a cautionary tale. Prologue: A week or two ago, I made patches to support <interface type='ethernet'> in the LXC driver. I did this not because I have a need for that, but because it seemed like the perfect avenue for investigating the best way to add IP address and route config to <interface>, as it is one environment where we have a need *and* the ability to setup IP info for both the host and guest sides of the interface. I accomplished this by simply generalizing the existing <interface type='bridge'> code to not attach the host-side veth device to a bridge. This makes all common attributes between type='ethernet' and type='bridge' consistent, including the configuration of guest-side and host-side device names, and here we come to the first inconsistency - the device name for the veth/tap on the host side is in the <target> element (which I've always been told is supposed to be used for device-specific info about how the device will be presented on the *guest* side, but I suppose this is because <interface type='direct'> uses <source dev='blah'> to provide the name of the physical device that the macvtap device (named in <target dev='macvblah'/> is attached to). And I guess because the dev attribute was already in-use in <target> the much more recently added guest-side name is given in the <guest> subelement (in LXC at least): <interface type='ethernet'> <target dev='hostblah'/> <-- name of veth on host side <guest dev='guestblah'/> <-- name of veth on guest side ... Now, this "is what it is". There is no changing it. In particular, the use of <target dev> for the host-side device name has been in use for so long and is so deeply ingrained that it's just part of the scenery. Moving for a minute to the IP address/route info for the guest side is already configured in the toplevel <ip> and <route> subelements of <interface>, <interface type='ethernet'> <ip address='1.2.3.4' .../> </interface> My first thought was to put the <ip> for the host side inside <source>: <interface type='ethernet'> <source> <ip address='1.2.3.5' .../> <-- host side </source> <ip address='1.2.3.4' .../> <-- guest side </interface> That makes sense to me because it parallels what we do with PCI addresses for hostdev - the PCI address in <source> tells what the address is on the host, and the one at the toplevel of <hostdev> tells what the PCI address will be in the guest. It *doesn't* fit well with the fact that the device we're setting up is named in <target> though, so we're already inconsistent, but putting the host-side IP config in <target> seems like an invitation to mix things up even more in the future, since <target> is used everywhere else as a place to put stuff related to what the device looks like in the guest (although... for <interface>, <target> *is* currently used only for the host-side tap/veth device name; so maybe we just can define the purpose of <target> differently in this one case... But I digress). So I went to the code to add parsing of <ip> inside <source>, and found that the type-specific data for ethernet has a dev, and that field in the object is set during parsing from <source dev='blah'/>, *and* that the openvz driver uses that dev name as the name of the network device in the *guest*! (even though my understanding of <source> is that it is supposed to be used for information about the *host* side of any device. Sigh.) So on openvz, we have this: <interface type='ethernet'> <target dev='hostblah'/> <-- name of interface on host side <source dev='guestblah'/> <-- name of interface on guest side ... which seems exactly the opposite of what it should be. Note that this doesn't seem to be documented anywhere except in the few lines in openvz_driver.c that implement it. (Note that, prior to commit 9a4b705f7 back in 2010, which added support for type='ethernet' in openvz, the "dev" field was already in the ethernet-specific sub-object of virDomainNetDef, but it was only used to hold the name of the bridge that a tap device was attached to when converting from a qemu commandline to XML (also, as previously stated, for type='direct' it is used to name the physical device on the host that the macvtap interface is connected to, i.e. *exactly* the opposite end of the chain). It looks like the poster of the openvz patch just saw an opportune existing-but-unused-by-type=ethernet attribute and took advantage, and it wasn't noticed in review). I'm actually skeptical that anyone even uses this, since openvz is a less-used driver, type='ethernet' is less used among interface types, and even after that it's valid to not provide a name, in which case one is automatically generated. But there is no way to verify that, so we're stuck with it. It is true that the LXC version of type='ethernet' was added only a few days ago, and there hasn't yet been a release, so I *could* modify it to be consistent with the attribute usage in the openvz driver. But that would make <interface type='ethernet'> in LXC inconsistent with <interface type='bridge'> in LXC, which is a much worse situation. IT seems there is nothing to change. As I said above "it is what it is". So why am I writing this message? Partly to just vent frustration (aka "whine") I suppose :-). Also partly as public testimony that my seemingly excessive worrying over attribute naming and placement is justified, and not just OCD. Also, as I said above, as a cautionary tale that any patch adding *any* XML config knob, or making use of an existing XML config knob needs extra scrutiny to help minimize such messes in the future.

[libvirt] [PATCH] unsetenv: relax to LGPLv2+
by Eric Blake 27 May '16

27 May '16

Especially since setenv is also LGPLv2+, and it makes sense for the two modules to stay in sync. Signed-off-by: Eric Blake <eblake(a)redhat.com> --- Libvirt wants LGPLv2+ when it uses gnulib, and recently ran into a problem where it can use the setenv module for mingw but not the unsetenv module. Barring any negative reviews, I'll push this in 24 hours, or sooner if I get a positive review; then libvirt will have to pick up the latest gnulib to make use of it. modules/unsetenv | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/modules/unsetenv b/modules/unsetenv index 015ac4e..909cec9 100644 --- a/modules/unsetenv +++ b/modules/unsetenv @@ -24,7 +24,7 @@ Include: <stdlib.h> License: -LGPL +LGPLv2+ Maintainer: all -- 2.5.5

[libvirt] [PATCH] lxc: Fix virLXCDomainObjBeginJob position in lxcDomainSetMemoryParameters
by Katerina Koukiou 27 May '16

27 May '16

Adjust the code to perform the virLXCDomainObjBeginJob first and then the call virDomainLiveConfigHelperMethod. As Ján Tomko pointed out, in virDomainLiveConfigHelperMethod, there is a check to see if the domain is active when AFFECT_LIVE is set. Since virLXCDomainObjBeginJob unlocks the virDomainObjPtr lock, the domain could possibly be destroyed while we wait for the job and the check results would no longer be valid.
