KVM call minutes for Jan 11

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



KVM Forum 2011
- expand the scope? yes, continue up the stack
- how long?  2 days (maybe 2 1/2 - 3 space permitting)
- where?  Vancouver with LinuxCon

Spice guest agent:
- virt agent, matahari, spice agent...what is in spice agent?
- spice char device
  - mouse, copy 'n paste, screen resolution change
- could be generic (at least input and copy/paste)
  - send protocol details of what is being sent
- need to look at how difficult it is to split it out from spice
  (how to split out in qemu vs. libspice)
- goal to converge on common framework
- more discussion on char device vs. protocol
  - eg. mouse_set breaks if mouse channel is part pv and part spice specific
- Alon will send link to protocol and try to propose new interfaces

migration and block devices:
- need to invalidate data after first read on target,
  because it can be stale
- close + reopen is what was done for NFS
- iscsi: can issue ioctl(BLKFLSBUF) to flush, but it's CAP_SYS_ADMIN only
- O_DIRECT to avoid cache (concerns that it's not guaranteed)
- agree change the default (cache=none for 

qemu patch queue is long:
- slow to return from break
- patience and more patch review will help make sure things are applied
  and don't fall through cracks
