Hi All,

I am running on CentOS Released 6.1 final. Been using and running Linux KVM quite well for quite some time, something goes wrong after I perform yum upgrade.

I created new VM yesterday without any problem, same exact installation procedure, installed FreeBSD 8.2. I tried to create a new VM today after yum upgrade, it's able to detect the hard disk, when I start commit FreeBSD 8.2 installation, it complains cannot write to disk as stated the error message below.

block I/O error in device 'drive-ide0-0-0': Invalid argument (22) block I/O error in device 'drive-ide0-0-0': Invalid argument (22) block I/O error in device 'drive-ide0-0-0': Invalid argument (22) block I/O error in device 'drive-ide0-0-0': Invalid argument (22) block I/O error in device 'drive-ide0-0-0': Invalid argument (22) block I/O error in device 'drive-ide0-0-0': Invalid argument (22)

Below is the log I capture from the VM log file

Any of you having the problem as well? I am planning to install CentOS as guest and see whether is has the same problem as well. Thanks.
