Hi All, The interface manual says - grant tables provide a generic mechanism sharing between domains. Subsequent lines suggest mechanism sharing between only unpriviliged domains. Can grant tables be used for this capability based shared memory communication between dom0 and domUs?

...ing problem when trying to boot another guest after less than a day of uptime. (the system started 15 guests at boot already which went fine). dom0 is allocated a fixed 1536M. Both host as pv guests run the same kernel, some hvm''s run a slightly older kernel (3.9 f.e.) The are quite some granttable messages in xl dmesg, i also included these and a "vmstat -m" -- Sander [54807.299791] xenwatch: page allocation failure: order:4, mode:0x10c0d0 [54807.317520] CPU: 5 PID: 54 Comm: xenwatch Not tainted 3.12.0-20131104 #1 [54807.334747] Hardware name: MSI MS-7640/890FXA-GD70 (MS-7640)...

Patrick, there following patches fix xenpaging for me. Granttable handling is incomplete. If a page is gone, a GNTST_eagain should be returned to the caller to inidcate the hypercall has to be retried after a while, until the page is available again. Please review.

The patch ''mem_event: use wait queue when ring is full'' I just sent out makes use of the waitqueue feature. There are two issues I get with the change applied: I think I got the logic right, and in my testing vcpu->pause_count drops to zero in p2m_mem_paging_resume(). But for some reason the vcpu does not make progress after the first wakeup. In my debugging there is one

Since the vTPM implementations are being incorproated into Xen and possibly upstream Linux, I would like to see if this protocol change could be added before we have significant legacy implementations. If not, I still think it would be useful as either a v2 or negotiated protocol change. The current vTPM protocol is a copy of the network protocol. This was likely done for ease of implementation,
