Package: qemu-kvm Version: 2.1+dfsg-2~bpo70+2 Severity: normal Hello,
I was able to successfully use the passthrough TRIM support with an IDE
interface virtual disk in Qemu-KVM version 2.0.
However after upgrading to 2.1 and restarting my VM, TRIM now fails in it with
messages like those quoted below (dmesg from the guest). There are no messages
in dmesg related to that on the host.
I run two VMs, and the other has not been restarted yet (it's running with the
old 2.0 binaries), and there TRIM works without issue. So it clearly seems to
be due to some change in 2.1.
