Hi all,
I had an action to set up a call on discussing the future direction of PCI Emulation. I CC’ed everyone who raised an interest. I propose to use Gotomeeting unless there are objections.
As far as I can tell, we have people in the following time-zones: PST to EST and BST. Not sure where Alexey is based, but it looks as if
16:00 – 17:00 BST
17:00 – 18:00 BST
18:00 – 19:00 BST
BST = UTC+1
may work. For me Mon, Wed and Fri’s generally work at those time-slots. Next week is a little busy for me, so I would prefer the following week. If you could fill out the following Google poll, if this week works that would be great. Otherwise please scream.
https://doodle.com/poll/gdnmcrvnibmw563n
If you are not on the CC list and want to be CC’ed on the invite, please add your e-mail address to the google poll (after your name)
Regards
Lars

Otherwise please scream. I'm afraid I'm on vacations from the 21st to the 29th of April, so I won't be able to join the meeting unless we move it to the week after.

I guess this will come later, but we need a clear agenda of items because the x86 and ARM topics are probably going to be completely different (albeit all related to PCI).

But I am happy to collate everything as for the x86 call and write up minutes On the x86 side: - Q35 HVM emulation, adding MCFG support to guests. - PVH guest pci-passthrough: using the internal vPCI infrastructure.

FTR - I had expressed an interest too; I can't really plan for the next week or two though at this point, so I'd join if I can whenever the meeting takes place.

FTR - I had expressed an interest too; I can't really plan for the next week or two though at this point, so I'd join if I can whenever the meeting takes place. Apologies: I must have missed this. The meeting is currently scheduled the 1st week of May, with May 2nd & 4th 17:00-18:00 BST (UTC+1) looking like the most promising options. This is outside the 1-2 week window you mention above. Unless I hear otherwise, I am assuming that week is fine.
