[Pkg-xen-devel] Bug#880554: #880554: max grant frames problem
Control: retitle -1 max grant frames problem (domu freeze with linux-image-4.9.0-4-amd64) Control: severity -1 important Control: reassign -1 src:xen 4.8.3+xsa267+shim4.10.1+xsa267-1+deb9u9 Just gardening here. (i) Bug title should mention grant frames. (ii) This does not affect all use cases and is not, IMO, RC. Although we should certainly see if we can improve it. (iii) Britney is confused because the bug was reassigned to xen-hypervisor-4.8-amd64 and thinks that updating to the 4.11-based packages from sid would help reduce RC bugs since they lack that .deb. This is wrong, of course. For this reason in general bugs should be reported against src:xen rather than against binary packages with Xen versions in their package name.

The 'xen/grant-table: max_grant_frames reached' should show up on the serial console. I'd like to see a test report of it actually happening. No further adjustments/fixes will go into the Stretch Xen packages at this stage. Having better documentation about how to set hypervisor and guest options to deal with all of this is still a TODO. I would really like to get some people together to start cleaning out the whole Xen related wiki section for Debian, and actually provide some helpful content, including FAQ stuff like max grants, PVH, PVH+grub etc... Whoever would want to participate in that, just reply a Yay! Doing documentation work might seem boring, but it's write once, read many all the way. Hans
