How about something like: "A new feature, VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS, has been added to the vhost-user protocol which, when negotiated, changes the way QEMU transmit memory regions to backend devices. Instead of sending all regions in a single VHOST_USER_SET_MEM_TABLE message, QEMU will send supporting backends individual VHOST_USER_ADD_MEM_REG and VHOST_USER_REM_MEM_REG messages to update the devices memory tables. VMs with vhost-user device backends which support this feature will not be subject to the max RAM slots limit of 8 and will be able to hot-add memory as many times as the target platform supports. Backends which do not support VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS are unaffected."
I don't have permission to edit the wiki. How can I get permission? Or can someone post it for me? On Wed, Jul 29, 2020 at 8:19 AM Michael S.
