[libvirt] [PATCH v2 0/5] admin: Introduce APIs to get/set client-related limits
by Erik Skultety
since v1:
- symbols added to libvirt_remote.syms
- APIs renamed
- dropped some unwanted client-side flags checks
- dropped unnecessary ifs before calling virAdmServerFree (because it handles
NULL gracefully)
- a man page entry virt-admin's commands created
Erik Skultety (5):
virnetserver: Introduce server's client-related limits getters
admin: Introduce some public constants related to server's client
limits
admin: Introduce virAdmServerGetClientLimits
admin: Introduce virAdmServerSetClientLimits
virt-admin: Introduce commands srv-clients-info and srv-clients-set

[libvirt] [PATCH] qemu: Don't lose VM runtime state on libvirt downgrade
by Cole Robinson
Run libvirtd from git with latest qemu, start a VM, stop libvirtd.
Run an older libvirtd version an you may see an error like:
qemuDomainObjPrivateXMLParse:857 : internal error: Unknown qemu capabilities flag device-tray-moved-event
Libvirt finds a cached capabilities flag it doesn't understand, and
fails to parse the VM runtime state. It now thinks the VM isn't
running, when it is. This is potentially serious since it could
lead to disk corruption if the VM is re-run.
For the common case of unknown qemu capabilities flags, treat an
unknown flag as non-fatal and continue on

[libvirt] [PATCH v4 0/3] Add AES Secret Object support (for RBD only)
by John Ferlan
v3:
http://www.redhat.com/archives/libvir-list/2016-May/msg00444.html
Changes since v3 (by patch)...
1. Separate out the mock for virRandomBytes. I realize this is not the
desired state, but figured to at least be prepared for what would be
coming as a followup to:
http://www.redhat.com/archives/libvir-list/2016-May/msg00735.html
that I'd at least adjust the code to follow using a different random
number generator (use increasing i instead of just 0xff for all)
2. Changes from code review... Change name from IV to AES, plus others
qemuDomainSecretAESSetup is variable based on HAVE_GNUTLS_CIPHER_ENCRYPT
Changes to utilize virStringEncodeBase64
Moved qemuDomainSecretSetup into this version (and made i
3. Split out mock (into patch 1)
Comment cleanup
Still unresolved from code review is a review comment in
qemuBuildDriveStr regarding where the desire movement was.
There's a very specific order to where the "password-secret=%s,"
can be placed. It just wasn't clear from the review comment
where exactly it was expected to "move" those lines

[libvirt] [PATCH 0/4] qemu: Assign addresses via virDomainDefPostParse
by Cole Robinson
This series adds a new domain post parse callback
virDomainDefAssignAddressesCallback, which we use in the qemu driver to
trigger qemuDomainAssignAddresses via PostParse. This streamlines
things a bit, but is also needed for some future work.
After this series, the only remaining open coded
qemuDomainAssignAddresses calls involve populating the runtime VM
address caches, which I discussesd here:

We cannot check ports if autoport is set because we set ports to 0 while

[libvirt] [PATCH v2 0/4] Don't disable auto_login for iSCSI targets
by John Ferlan
v1: http://www.redhat.com/archives/libvir-list/2016-May/msg01027.html
Changes since v2:
* Patch 2
* Remove the 'str' fetch/free - it was unnecessary
* Initialize and free 'error'
* Did not adjust reported error since with the usage of exitstatus
the call to virCommandRunRegex, that means the virCommandWait code
will return the error rather than reporting it. So the reporting is
left to this code to handle. Kept the same error code (INTERNAL) as
virCommandWait
Patch 3-5
* Remove 3, combine 4 & 5, but remove the setting of the autologin for
libvirt managed targets. This is essentially Fritz's initial patch:
http://www.redhat.com/archives/libvir-list/2016-May/msg00002.html
but with the adjustment to add the "ATTRIBUTE_UNUSED" for the
initiatoriqn parameter (it'll be removed in the next patch as
it is a bit more invasive).
Fritz Elfert (1):
util: Remove disabling of autologin for iscsi-targets
John Ferlan (3):
util: Add exitstatus parameter to virCommandRunRegex
iscsi: Add exit status checking for virISCSIGetSession
iscsi: Remove initiatoriqn from virISCSIScanTargets
