B Z #116 2784
With this release, VDSM private keys are no longer collected by
sosreports.
B Z #1053114
Previously, extracting information on networks took a long time
when there were multiple networks defined on the host. Using a
host with 200+ networks was very slow or impossible. Now, the code
has been refactored with attention to asymptotic time efficiency,
so that 1000 networks are workable.
B Z #1072030
Previously, missing unit conversion caused the reported shared
memory amount to be much higher than expected. Proper unit
conversion has now been added, resulting in accurate shared
memory amount reporting.
B Z #109 76 74
Previously, a change was introduced that prevented a bond's IP
from being cleared when a new one was being set, causing the new
IP address to be configured as secondary, alongside the previous
one, instead of as the sole primary IP address. Now, the previous
IP bonding configuration is removed when reconfiguring the IP, so
that there are no leftover IPs from previous configurations.
B Z #1173257
Previously, it took a couple of seconds to collect the memory and
balloon information of a virtual machine that had just finished
migration. This caused MOM to receive zeros and subsequently try
to set the balloon size to zero. The guest operating system then
returned all memory it could and crashed with kernel panic once
the kernel needed to allocate some buffer. Now, VDSM does not
report any ballooning information (not even zero) until it
collects the necessary data, so migrating ballooned hosts works
properly.
B Z #1136 9 82
Previously, a naming issue caused a permanent communication
disruption with certain guest virtual machines until the complete
stop and restart of the affected virtual machine. This problem has
been now resolved.
B Z #1101021
Previously, a timing issue caused a permanent communication
disruption with all guest virtual machines until the restart of
the VDSM process. This problem has been now resolved.
