vdsm 3.5.1 - bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

Updated vdsm packages that fix several bugs and add various enhancements are now
available.

Description

VDSM is a management module that serves as a Red Hat Enterprise Virtualization
Manager agent on Red Hat Enterprise Virtualization Hypervisor or Red Hat
Enterprise Linux hosts.

Changes to the vdsm component:

• Libvirt 1.2.8 introduced a regression where disk type is converted from
  "block" to "file" after live storage migration. This breaks the disk extension
  logic, leading to unwanted extension using all free space in the storage domain.
  

libvirt-daemon-1.2.8-16.el7_1.1 and libvirt-python-1.2.8-6.el7_1.1 fixed this
issue by adding a new flag. RHEV-3.5.1 uses the new flag when available, fixing
this issue; however, the fix in RHEV-3.5.1 is effective only when using fixed
versions of libvirt-daemon and libvirt-python.

Do not perform live storage migration on block storage in RHEL 7.1 unless you
have the fixed version of libvirt-daemon (libvirt-daemon-1.2.8-16.el7_1.1) and
libvirt-python (libvirt-python-1.2.8-6.el7_1.1). These versions should be
available as a zero-day async release with RHEL 7.1. (BZ#1196049)

• After adopting Red Hat Enterprise Linux 7 and systemd, the work of preparing
  the environment before the VDSM service starts was managed by systemd itself
  using the ExecStartPre API. This preparation work was implemented under
  vdsm_init_common.sh and included network restoration. On DHCP networks, a side
  effect of this was the spawning of a dhclient daemon by init scripts. Since
  ExecStartPre API prohibits long-running processes, systemd kills those processes
  silently, leaving hosts with no dhclient to renew their IP lease. Now, the
  network restoration part of the preparation work is delegated to another
  dependent systemd unit resulting in a new 'oneshot' type service that is a vdsmd
  dependency, called 'vdsm-network'. Also systemd is now told not to kill dhclient
  processes upon stopping vdsm-network service. (BZ#1204782)
  
• An unversioned hotfix of the communication protocol between the Red Hat
  Enterprise Virtualization Manager and virtualization hosts resulted in
  exceptions in engine-log, and caused the Manager to be unable to communicate
  with hosts. To avoid this, when using Manager to host communication via JSON-RPC
  (which is new in 3.5), you must update the Manager to the new version before
  updating the virtualization hosts. Any host using JSON-RPC can only be upgraded
  once the new engine release is running. Alternatively, configure the Manager to
  use XML-RPC instead. (BZ#1196735)
  
• Previously, live migration of a virtual machine with an external provider
  network (OpenStack Neutron) attached failed if security groups were set, because
  the 'vdsm-hook-openstack' hook was not able to handle this. Now, the hook is
  able to handle security groups properly on source and destination hosts, and
  virtual machines can be live migrated with an external provider network
  attached. (BZ#1196077)
  
• Previously, 'hosted-engine' called the VDSM wrapping 'vdsClient' utility over
  SSL, which caused SSL timeout errors for long sync commands. Now, the 'vdscli'
  library is used instead of 'vdsClient', and this prevents SSL timeouts.
  (BZ#1190207)
  
• Previously, when upgrading hosts from 3.4.x to 3.5.0 using 'yum update vdsm',
  VDSM was not restarted; as a result, the next time VDSM was restarted, it
  failed, and manual steps had to be performed to restore the service. Now, this
  issue has been resolved, and upgrading hosts from 3.4.x to 3.5.0 succeeds.
  

Note: This issue did not apply to using the 'Reinstall' button in the
Administration Portal. (BZ#1208752)
