[libvirt] [PATCH] fix regex to check CN from server certificate
by Tiago M. Vieira 09 Feb '18

09 Feb '18

Currently when the script validates the PKI files and the certificate 'Subject:' field contains RDNs after the Common Name (CN), these values are also included, creating a false result that the CN is not correct. A small change to the sed regex fixes this issue, by extracting only the value for CN and nothing else. The regex is replaced with the exact same regex used to extract the CN value from the client certificate. --- tools/virt-pki-validate.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/virt-pki-validate.in b/tools/virt-pki-validate.in index 206637abf..b04680dde 100755 --- a/tools/virt-pki-validate.in +++ b/tools/virt-pki-validate.in @@ -255,7 +255,7 @@ then echo CA organization: $ORG echo Server organization: $S_ORG fi - S_HOST=`"$CERTOOL" -i --infile "$LIBVIRT/servercert.pem" | grep Subject: | sed 's+.*CN=$[a-zA-Z\. _-]*$+\1+'` + S_HOST=`"$CERTOOL" -i --infile "$LIBVIRT/servercert.pem" | grep Subject: | sed 's+.*CN=$.[a-zA-Z \._-]*$.*+\1+'` if test "$S_HOST" != "`hostname -s`" && test "$S_HOST" != "`hostname`" then echo The server certificate does not seem to match the host name -- 2.14.3

[libvirt] [tck PATCH 0/9] Fix libvirt-tck nwfilter tests
by Laine Stump 09 Feb '18

09 Feb '18

libvirt-tck happens to have the most thorough set of nwfilter tests around. Unfortunately they haven't been run in quite awhile, and have suffered from some bit rot. This patch series (along with Dan's patch to force virt-builder to redo selinux labels after installing extra packages) gets the nwfilter tests all completing successfully again *on a Fedora 26 host* with libvirt 3.2.1 and libvirt 4.0.0+. The concurrency tests (at least) still fail on an F27 host - in that case they are actually revealing a bug due to something in libvirt, libpcap, or maybe the kernel (and since the kernels in F26 and F27 are nearly the same, and I tried both of the above libvirt versions on F27 with the same failure (two threads hung in a polling loop in libpcap) Once I got this all running, I noticed that there are several domain and network tests that are failing, and at least the ones I looked into were due to bugs in the tests (e.g. the netdev hotplug test uses multicast MAC addresses, and assumes that device detaches are synchronous), so there's more work to do, but the nwfilter tests are what's most important right now.

[libvirt] [PATCH] qemu: report a nicer error when USB is disabled
by Ján Tomko 09 Feb '18

If the user tries to define a domain that has <controller type='usb' model='none'/> and also some USB devices, we report an error: error: internal error: No free USB ports Which is technically still correct for a domain with no USB ports.

[libvirt] [PATCH] Migration: Preserve the failed job in case migration job is terminated beyond the perform phase.
by Prerna Saxena 09 Feb '18

09 Feb '18

In case of non-p2p migration, in case libvirt client gets disconnected from source libvirt after PERFORM phase is over, the daemon just resets the current migration job. However, the VM could be left paused on both source and destination in such case. In case the client reconnects and queries migration status, the job has been blanked out from source libvirt, and this reconnected client has no clear way of figuring out if an unclean migration had previously been aborted. This patch calls out a "potentially" incomplete migration as a failed job, so that a client may be able to watch previously failed jobs for this VM and take corrective actions as needed.

[libvirt] [PATCH 0/7] Keep non-persistent changes alive in snapshot
by Kothapally Madhu Pavan 09 Feb '18

09 Feb '18

Restoring to a snapshot should not overwrite the persistent XML configuration of a snapshot as a side effect. This patchset fixes the same. Currently, virDomainSnapshotDef only saves active domain definition of the guest. And on restore the active domain definition is used as both active and inactive domain definitions. This will make the non-persistent changes persistent in snapshot image. This patchset allows to save inactive domain definition as well and on snapshot-revert non-persistent configuration is restored as is. Currently, snapshot-revert is making non-presistent changes as persistent. Here are the steps to reproduce. Step1: virsh define $dom Step2: virsh attach-device $dom $memory-device.xml --live Step3: virsh snapshot-create $dom Step4: virsh destroy $dom Step5: virsh snapshot-revert $dom $snapshot-name Step6: virsh destroy $dom Step7: virsh start $dom Here we still have $memory-device attached in Step2. This patchset is attempting to solve this issue. This patchset will also allow user to dump and edit inactive XML configuration of a snapshot. Dumping inactive domain definition of a snapshot is important as --redefine uses snapshot-dumpxml output to redefine a snapshot.

Hopefully I covered what's necessary... Essentially a bunch of copying of existing examples... I haven't been able to actually build an RPM locally for a long time, but this does work with make install at least (or at least it worked in the environment I tried it on).

[libvirt] [PATCH python 1/1] Fix type extracting from PyDict
by Edgar Kaziakhmedov 08 Feb '18

08 Feb '18

PyInt_Check returns value whether or not an input object is the integer type. The existing implementation of extracting leads to the wrong type interpretation in the following code: params = {libvirt.VIR_MIGRATE_PARAM_DISKS_PORT : 50123} ... dom.migrate3(%option1, params, %option3) where libvirt reports: libvirt.libvirtError: invalid argument: invalid type 'ullong' for parameter 'disks_port', expected 'int' So, this patch fixes that bug and allows casting to the VIR_TYPED_PARAM_INT type.
