However, 2 bad things have happened: 1) In my Linux DomU, my fio randomwrite test have gone from about 28k iops to about 800 iops. Can this be fixed? changing bs and ba to 512 in the fio config file didn't hep. 2) The windows setup didn't complain that it couldn't install on the LV, but once I clicked 'next', the Dom0 crashed and the server rebooted. A lot of output was displayed on screen but quickly vanished as the system rebooted. I'm trying to see if the output was saved anywhere. Any ideas why this could of happened and/or where the output might be saved? Thanks
