Liberty 시리즈에 대한 릴리즈 노트¶
The qemu-img tool now has resource limits applied which prevent it from using more than 1GB of address space or more than 2 seconds of CPU time. This provides protection against denial of service attacks from maliciously crafted or corrupted disk images. oslo.concurrency>=2.6.1 is required for this fix.
recordconfiguration option for the console proxy services (like VNC, serial, spice) is changed from boolean to string. It specifies the filename that will be used for recording websocket frames.
When plugging virtual interfaces of type vhost-user the MTU value will not be applied to the interface by nova. vhost-user ports exist only in userspace and are not backed by kernel netdevs, for this reason it is not possible to set the mtu on a vhost-user interface using standard tools such as ifconfig or ip link.
The 12.0.1 release contains fixes for two security issues.
Fixes a bug where Nova services won’t recover after a temporary DB connection issue, when service group DB driver is used together with local conductor, as the driver only handles RPC timeout errors.

Fixes a bug where Nova services won’t recover after a temporary DB / MQ connection issue, when service group DB driver is used together with remote conductor, as the driver only handles RPC timeout errors and does not account for other types of errors (e.g. wrapped DB errors on the remote conductor transported over RPC)
