Hi all,
  Recently, I am testing the TMEM support on Xen. I discovered that when enabled TMEM in ubuntu 14.10 as guest on Xen 4.1 & Xen 4.3, "xm save" & "xm restoreâ failed after there are more than 1000 pages put in persistent pool of TMEM in Xen. My operations are list as follows: In ubuntu guest (8 cores , 8GB): sudo modprobe tmem (than wait for the selfballoon to finish) dd if=/dev/zero of=/tmp/test.img bs=10M count=1000 dd if=/tmp/test.img of=/dev/null bs=10M dd if=/tmp/test.img of=/dev/null bs=10M ......... (until more than 1000 pages put in persistent pool) In Domain 0: (add tmem in grub.cfg) xm save ubuntu test.save xm restore ubuntu test.save When TMEM is not enabled, save & restore success after these operations. But if TMEM is enabled, save & restore fail. Does anyone test about save & restore when enabled TMEM in Xen?? Is there anything I do wrong? Thanks!!
