[one-users] KVM Qemu does not mount DATABLOCK.

[Leong Marco]

Hi Ruben,

Very appreciate for your reply.

Unfortunately, even I have put all three disk to VIRTIO. It still not working. If I use ide, it seems that it is not able to have more than one IDE device. And SCSI was not supported by CentOS 5.5's kernel. 

Any idea to get around this?

Thank You !
