Subject: [Qemu-devel] IO errors in guest caused by LTP dio test
Date: Wed, 22 Jun 2011 16:36:17 -0700 [thread overview]
Message-ID: <m27h8dh21a.fsf@firstfloor.org> (raw)
Running LTP testcases/kernel/io/direct_io/test_dma_thread_diotest7
causes IO errors in the guest. There are no IO errors on the host.
Kernel Linux 3.0.0-rc*
Using a standard emulated IDE -hda image.
I tried a few qemu versions, it happens at least with the one
in FC14 and with 0.14. qemu master doesn't boot and ends
with a spinlock lockup.
