Qemu>=5.0.0 bumped the default tb-cache size to 1GiB(from 32MiB) and this made it difficult to run multiple guest VMs on systems running with lower memory. With Libvirt>=8.0.0 it's possible to configure lower tb-cache size. Below config option is introduced to allow configure TB cache size as per environment needs, this only applies to 'virt_type=qemu':- [libvirt]tb_cache_size Also enable this flag in nova-next job.

Qemu>=5.0.0 bumped the default tb-cache size to 1GiB(from 32MiB) and this
|
|
made it difficult to run multiple guest VMs on systems running with lower
|
|
memory. With Libvirt>=8.0.0 it's possible to configure lower tb-cache
|
|
size. A new config option is introduced:
|
|
|
|
``[libvirt]tb_cache_size``
|
|
|
|
This config option can be used to configure tb_cache size
|
|
for guest VMs, it's only applicable with ``virt_type=qemu``.
