[Xen-devel] [PATCH] pv-grub: fix boot crash when no fb is available
pv-grub: fix boot crash when no fb is available
When no fb is available, init_fbfront will return, so the local
semaphore for synchronization with the kbd thread would get dropped.
Using a global static semaphore instead fixes this.

I don''t really have the time to investigate further in the blktap2 code to know which end is behaving badly (I do not even know where the PV part of it is). What I do know is that according to xenstore-ls, MiniOS says it''s initialized, but the backend seems stuck in the initwait state, I don''t know what it is waiting for.

It''s all blkback instances sitting on a blktap2 node, which provides a block device node. The disk I''m running for development purposes is set up as follows: disk = [ "tap:tapdisk:aio:/var/tmp/lenny.ext,xvda,w" ] Took me a while to figure the syntax out, not sure if different ones like yours work too.> Or maybe it falls back to plain blkback?Could be... What major number do you see in the physical-device XS node? That config thing is clearly a nightmare.

I managed to solve the booting to the grub prompt issue (apparently pvgrub can''t handle symlinks). The issue now though is that my image that works fine as an HVM seems to hang. I''ve pasted the output below. In there you can see that there is a call trace for something xen related early on in the kernel boot process. I''m unsure if this is related to some of the other pvgrub problems I''ve been seeing on the list as of late.

Re: [Xen-devel] Re: [PATCH] pv-grub: fix boot crash when no fb is available
Hello, You should perhaps test again with the 83fe79c0225f pv-grub: Fix for incorrect dom->p2m_host[] list initialization fix, as it could very be a culprit.
