[libvirt] [PATCH] qemu: check for active domain after agent interaction
by Eric Blake 22 Aug '14

22 Aug '14

Commit b606bbb41 reminded me that any time we drop locks to run back-to-back guest interaction commands, we have to check that the guest didn't disappear in between the two commands. A quick audit found a couple of spots that were missing this check. * src/qemu/qemu_driver.c (qemuDomainShutdownFlags) (qemuDomainSetVcpusFlags): Check that domain is still up. Signed-off-by: Eric Blake <eblake(a)redhat.com> --- I found this by inspection, and did not try to actually reproduce if it would cause failures.

[libvirt] [PATCH v2 0/3] Wrong allocation size displayed for NFS volumes
by John Ferlan 22 Aug '14

22 Aug '14

Changes over v1 - different tact as more research discovers that the posix_fallocate() does not perform the correct pre-allocation of space for an NFS backed file/disk, some details of the findings can be found: http://www.redhat.com/archives/libvir-list/2014-August/msg00367.html The first patch in this series will refactor the safezero to allow for more fallback than the current code. Initially implemented as a series of three 'safezero()' functions in commit id 'c29d0929' using build conditionals to determine which of the 3 is being used. The refactored code will have one function that will make a series of calls rather the just failing on whatever is built into the system. The first is a global virFileFdPosixFallocate() with the build conditional controlling only whether the function runs or will just return -1. It will also be re-used by the Volume Resize code in a future patch. If on creation the virFileFdPosixFallocate() fails, attempts will be made to then try the mmap() method (if it exists), and then fall back to the slow, old, safewrite of zero filled buffers. The mmap function will follow the format of the posix_fallocate insomuch as if HAVE_MMAP is defined, then that will be attempted or a -1 will be returned immediately. The major change of this patch over the prior code is the fallback. One other minor change is if the virFileFdPosixFallocate() tries to call posix_fallocate() and fails, then a VIR_WARN will be used to indicate something went wrong. Previously, the code would return errno and eventually that would filter back to a caller which would use the errno in a sys error message. This I think only is odd when it comes to the resize path. The second patch looks to resolve the first issue discovered by: https://bugzilla.redhat.com/show_bug.cgi?id=1077068 It does this by checking the returned size/len of the file in the posix_fallocate() call and if it does not match a VIR_WARN will be posted and a failure returned allowing either the mmap or write of zero filled buffers to the file. The third patch changes the virStorageFileResize() logic to follow the safezero() logic with respect to build conditionals. Also, rather than reinvent the wheel, it will reuse the virFileFdPosixFallocate(). The new static API resizeSysFallocate() will return -1 if the build conditionals are not met. A current "downside" is by calling virFileFdPosixFallocate() twice (once directly and the other indirectly through safezero), the VIR_WARN will be displayed twice, but that should only affect someone trying to debug things. NOTE: Investigation and testing while creating this series also showed it's possible to modify the NFS Pool Start code to add a "-o wsize=4096" to the MOUNT command in order to force smaller write's. While that did fix the symptoms, the fix just didn't "feel right". The block size of the "source" export was 4096 bytes, while the block size of the "target" file was 1048576 bytes (current NFSv4 wsize default value when not specified). Whether those play into what posix_fallocate() does I am not sure, but if it does and that's fixed, then the way these patches are coded up - it won't matter. Compared to perhaps needing to revisit or document heavily how to set some new field in the pool XML source - this just seems more right.

[libvirt] [PATCHv3] numatune: setting --mode does not work well
by Erik Skultety 22 Aug '14

22 Aug '14

When trying to set numatune mode directly using virsh numatune command, correct error is raised, however numatune structure was not deallocated, thus resulting in creating an empty numatune element in the guest XML, if none was present before.

[libvirt] [PATCH] iotune: setting an invalid value now reports error
by Erik Skultety 22 Aug '14

22 Aug '14

When trying to set an invalid value into iotune element, standard behavior was to not report any error, rather to reset all affected subelements of the iotune element back to 0 which results in ignoring those particular subelements by XML generator. Patch further examines the return code of the virXPathULongLong function and in case of an invalid non-integer value raises an error. Fixed to preserve consistency with invalid value checking of other elements.

[libvirt] RFC: sVirt disk isolation with network based storage
by Daniel P. Berrange 22 Aug '14

22 Aug '14

As everyone knows sVirt is our nice solution to isolating guest resources from other (malicious) guests through SELinux labelling of the appropriate files / device nodes. This has been pretty effective since we introduced it to libvirt. In the last year or two, particularly in the cloud arena, there has been a big shift towards use of network based storage. Initially we were relying on kernel drivers / FUSE layers that exposed this network storage as devices or nodes in the host filesystem, so sVirt still stood a chance of being useful if the devices /FUSE layer supported labelling. Now though QEMU has native support for talking to gluster, ceph/rbd, iscsi and even nfs servers. This support is increasingly used in preference to using the kernel drivers / FUSE layers since it provides a simpler and thus (in theory) better performing I/O path for the network storage and does not require any privileged setup tasks on the host ahead of time. The problem is that I beleive this is blowing a decent sized hole in our sVirt isolation story. eg when we launch QEMU with an argument like this: -drive 'file=rbd:pool/image:auth_supported=none:\ mon_host=mon1.example.org\:6321\;mon2.example.org\:6322\;\ mon3.example.org\:6322,if=virtio,format=raw' We are trusting QEMU to only ever access the disk volume 'pool/image'. There are, in all likelihood, many 100's or 1000's of disk images on the server it is connecting to and nothing is stopping QEMU from accessing any of them AFAICT. There is no currrently implemented mechanism by which the sVirt label that QEMU runs under is made available to the remote RBD server to use for enforcement, nor any way in which libvirt could tell the RBD server which label was applied for which disk. The same seems to apply for Gluster, iSCSI, and NFS too when accessed directly from a network client inside the QEMU process. As it stands the only approach I see for isolating each virtual machines disk(s) from other virtual machines is to make use of user authentication with these services. eg each virtual machine would need to have its own dedicated user account on the RBD/Gluster/iSCSI/NFS server, and the disk volumes for the VM would have to be made accessible solely to that user account. Assuming such user account / disk mapping exists in the servers today that can be made to work but it is an incredibly awful solution to deal with when VMs are being dynamically created & deleted very frequently. Today apps like OpenStack just have a single RBD username and password for everything they do. Any virtual machines running with RBD storage on OpenStack thus have no sVirt protection for their disk images AFAICT. To protect images OpenStack would have to dynamically create & delete new user accounts on the RBD server & setup disk access for them. I don't see that kind of approach being viable. IIUC, there is some mechanism at the IP stack level where the kernel can take the SELinux label of the process that establishes the network connection and pass it across to the server. If there was a way in the RBD API for libvirt to label the volumes, then potentially we could have a system where the RBD server did sVirt enforcement, based on the instructions from libvirt & the label of the client process. Thoughts on what to do about this ? Network based storage, where the network client is inside each QEMU server, is here to stay so I don't think we can ignore the problem long term.

[libvirt] [PATCHv2] numatune: setting --mode does not work well
by Erik Skultety 21 Aug '14

21 Aug '14

When trying to set numatune mode directly using virsh numatune command, correct error is raised, however numatune structure was not deallocated, thus resulting in creating an empty numatune element in the guest XML, if none was present before. Running the same command aftewards results in a successful change with broken XML structure. Patch fixes the deallocation problem as well as checking for invalid attribute combination VIR_DOMAIN_NUMATUNE_PLACEMENT_AUTO + a nonempty nodeset.

[libvirt] [PATCH] conf: net: Correctly switch how to format address fields
by Peter Krempa 21 Aug '14

21 Aug '14

When formatting the forward mode addresses or interfaces the switch was done based on the type of the network rather than of the type of the individual <interface>/<address> element. In case a user would specify an incorrect network type ("passhtrough") with <address> elements, libvirtd would crash as it would attempt to format an <interface>. Use the type of the individual element to format the XML. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1132347 --- The parser would be better of with a refactor.

[libvirt] [PATCH v2] Perform disk config validity checking for attach-device config
by John Ferlan 21 Aug '14

21 Aug '14

https://bugzilla.redhat.com/show_bug.cgi?id=1078126 Using 'virsh attach-device --config' (or --persistent) to attach a file backed lun device will succeed; however, subsequent domain restarts will result in failure because the configuration of a file backed lun is not supported. Although allowing 'illegal configurations' is something that can be allowed, it may not be practical in this case. Generally, when attaching a device to a domain means the domain must be running. A way around this is using the --config (or --persistent) option. When an attach is done to a running domain, a temporary configuration is modified first followed by the live update. The live update will make a number of disk validity checks when building the qemu command to attach the disk. If any fail, then change is rejected. Rather than allow a potentially illegal combination, adjust the code in the configuration path to make the same checks as the running path will make with respect to disk validity checks. This way we avoid having the potential for some subsequent start/reboot to fail because an illegal combination was allowed. NB: The live path still checks the configuration since it is possible to just do --live guest modification...
