Subject: Re: raw disks no longer work in latest kvm (kvm-88 was fine)
Date: Sat, 22 May 2010 17:44:25 +0700 [thread overview]
Message-ID: <4BF7B589.1070808@nagafix.co.uk> (raw)
In-Reply-To: <4BBE51F4.6070904@nagafix.co.uk>
Bump.
Now that qemu is less likely to eat my data, " *[Qemu-devel] [PATCH 4/8]
block: fix sector comparism in*"
http://marc.info/?l=qemu-devel&m=127436114712437
I thought I would try using the raw 1.5TB partition again with KVM,
still no go.
I am still having to use:
#undef CONFIG_PREADV
Host and guest kernel version is 2.6.34, headers 2.6.33, glibc 2.10.1-r1
qemu-kvm 0.12.4 + patch above.
Who do I need to bug? glibc? kvm?
Thanks
Antoine
