We are set up CENTOS 5.2 (X86) as our database server.? I created raw partitions and also put definition on /etc/sysconfig/rawdevices. I can use "raw -qa" see raw partitions.? The wield things is after reboot /dev/raw is not exist any more. ? Does anyone know how to fix it? ? Thanks.

However, you still would not be able to issue SCSI reservations unless you run QEMU with the CAP_SYS_RAWIO capability (using "<disk ... rawio='yes'>"). Most important, it still would be unsafe to do this if the same device is passed to multiple virtual machines on the same host. You need to have NPIV and create separate virtual HBAs. Then each virtual machine should get a sepa...

...lack of capability. Please check if enough capability was added to kvm process by the following steps. 1. Check the pid of kvm process. # ps -C qemu-system-x86_64 -o pid= 5177 2. Check the capability for the process. # getpcaps 5177 Capabilities for `5177': = cap_sys_rawio+i In my fedora19 environment, as seen in above, only cap_sys_rawio+i was added with rawio='yes'. Even though, cap_sys_rawio+ep is required to pass-through SCSI Reservation from the guest. Note that I succeeded to pass-through SCSI Reservation with the following steps in my environment,...
