I'm trying to modify the amount of RAM that has some of guests. Host has 2.6.30 kernel with KVM-88. In one of guest I didn't have problems when decreasing the amount of memory =66rom 3584 MIB to 1024 MiB. This guest has 2.6.26-2-686 stock kernel. Also= I was trying to decrease the amount RAM of another guest from 3584 MiB to 2048 MiB, but it didn't work. This other guest has 2.6.24-etchnhalf.1-686-bigmem stock kernel. Does Ballooning in guest require 2.6.25 or superior? Thinking that it could be an impediment related to the kernel version of guest, I tried to increase the memory of another one guest with 2.6.26-2-686 from 512 MIB to 1024 MIB, but this didn't work either. These are the statistics of of memory usage in host: # free total used free shared buffers cached Mem: 16469828 14763460 1706368 0 7800712 202044 -/+ buffers/cache: 6760704 9709124 Swap: 8319948 19240 8300708 Which can be the cause? Thanks in advance for your reply.
