I am going to have to work on my technical writing. Apparently, I did not make it clear that I have my VM's off when I do my backups. It is when XP's VM has previously run that I have a problem. And, KVM is now off the hook, because, I am doing a backup and I have not fired off a single VM this boot cycle, and ... DUMP: Volume 1 started with block 1 at: Sat Jul 7 22:59:37 2012 DUMP: dumping (Pass III) [directories] DUMP: dumping (Pass IV) [regular files] DUMP: 1.19% done at 11362 kB/s, finished in 6:56 DUMP: 2.62% done at 12559 kB/s, finished in 6:11 DUMP: 4.05% done at 12953 kB/s, finished in 5:54 It is doing its five times slower thing. I wonder if there is something coincidentally I do that is causing the slowdown that I typically do it when I am running XP, maybe like listen to music while I work, or something else. I am going to have to pay close attention to what I have run on the Linux side when I have XP up. The game is a foot! -T
