Bug#693851: Xen domU dynamic memory extension not working
Package: linux-image-2.6.32-5-xen-amd64
Version: 2.6.32-5
The dynamic memory extension is not working on PV domU kernel
linux-image-2.6.32-5-xen-amd64 nor linux-image-2.6.32-5-amd64, but it's
working once the domU is booting with linux-image-2.6.26-2-xen-amd64.
During the investigation we discovered that the 'target' is updated
correctly on dom0 and also
/sys/devices/system/xen_memory/xen_memory0/target_kb file is correctly
updated on domU - the only issue is that domU kernel do not make this
memory 'change' effective.
The shrink of memory is working well - only the increase above the
initial memory value is not working - the same as expected on HVM guests.
dom0 is booting linux-image-2.6.32-5-xen-amd64 and Debian's Xen 4.0.1 is
installed on the system.
There is long discussion [1] on the xen-users mailing list with no root
cause found.
Attached are domU and dom0 dmesg outputs.
