Icon Info.png This is a community changelog, describing minor internal changes, which can be interested for ISPs or XCP power users. It typically covers information that were not covered in the product release notes. Feel free to add. We will regularly poll it and migrate items to XCP 1.6 release notes.


Console

  • new command: xe console vm=....
  • vm: other-config:disable_pv_vnc is no longer supported
  • vncterm can provide telnet-like access to VM consoles (PV only?), called 'tc'. Port can be found in xenstore /local/domain/ID/console/tc-port.

OVS

  • OVS 1.4.2, main changes:
    • no memory leak on heavy load with many flows
    • normal ipv6 support for ovs-ofctl
  • new service /usr/bin/python /usr/share/openvswitch/scripts/ovs-xapi-sync

IP/MAC antispoofing

  • new values in vif:
               locking-mode ( RW): locked
               ipv4-allowed (SRW): X.X.X.X
               ipv6-allowed (SRW): YY:YY:YY::YY:YY
  • new vif initialization script: /opt/xensource/libexec/setup-vif-rules

Logging

  • new log with xen log ring buffer content: /var/log/xen-dmesg

Xen behavior

  • XCP now disable C-states on CPU with errors in powersaving routines. It appears in xen log:
(XEN) Disabling C-states C3 and C6 on Nehalem Processors due to errata

Release Notes Errata

VHD/VDI

  • snapwatchd daemon removed. VHD tree is coalesed (still not known all cases - at least at the xe sr-scan).
  • 'Base copy' now named after the original disk name. No longer 'base copy' in name-label
  • vhd coalesing now never remove last base copy (even there is no snapshots or any other reason for splitting). To reduce space usage create new snapshot, delete it, exec xe sr-scan and wait until 'old' and 'new' base copy (disk content prior snapshot creation) will be merged. Disk still gonna continue to grow (base copy is always read only).
