The "PVHVM" image appears to have disappeared from RAX, replaced with a "Cloud" image. Maybe I haven't looked in the right place, but I can't find any info on if, why or when this was updated. But I started a server with the "Cloud" image and it seems the same as the PVHVM image to me; hdparm showed read speads the same as a older server and dd writes to a file were the same speed (recorded below for posterity). ianw@nb04:~$ dd if=/dev/zero of=testfile bs=1G count=1 oflag=direct 1+0 records in 1+0 records out 1073741824 bytes (1.1 GB, 1.0 GiB) copied, 5.21766 s, 206 MB/s ianw@nb04:~$ sudo hdparm -Tt /dev/xvda /dev/xvda: Timing cached reads: 16428 MB in 1.99 seconds = 8263.05 MB/sec Timing buffered disk reads: 752 MB in 3.00 seconds = 250.65 MB/sec From looking at dmesg it has [ 0.000000] DMI: Xen HVM domU, BIOS 4.1.5 11/28/2013 [ 0.000000] Hypervisor detected: Xen HVM [ 0.000000] Xen version 4.1.
