Subject: [Qemu-devel] ahci-test failures with 'Failed to get "write" lock'
Date: Thu, 15 Jun 2017 16:28:52 +0100 [thread overview]
Message-ID: <20170615152852.GB2399@work-vm> (raw)
Hi,
Peter noticed that there were some hangs in the ahci-test;
I can reproduce them on my laptop as long as the laptop has
some other load on it (a few md5sum /dev/zero's help).
/x86_64/ahci/flush/migrate: qemu-system-x86_64: Failed to get "write" lock
Is another process using the image?
OK
/x86_64/ahci/migrate/sanity: qemu-system-x86_64: Failed to get "write" lock
Is another process using the image?
and that hangs in sanity.
That seems to be the common case, I've also had one:
/x86_64/ahci/migrate/ncq/halted: qemu-system-x86_64: Failed to get "write" lock
Is another process using the image?
qemu-system-x86_64: /home/dgilbert/git/qemu/block/io.c:1352: bdrv_aligned_pwritev: Assertion `child->perm & BLK_PERM_WRITE' failed.
Neither of these always fail.
Dave
