Hi,
i'm playing a bit around with my domains and the balloon driver.
To get information about ballooning i use virsh dommemstat.
But i only get very few information:
virsh # dommemstat vm_idcc_devel
actual 1044480
last_update 0
rss 1030144
Also configuring "dommemstat --domain vm_idcc_devel --period 5 --live"
or "dommemstat --domain vm_idcc_devel --period 5 --current" does
neither update nor extend the information.
In vm_idcc_devel virtio_balloon is loaded:
idcc-devel:~ # lsmod|grep balloon
virtio_balloon 22788 0
Guest OS is SLES 10 SP4. Is that too old ?
Host OS is SLES 12 SP5.
There are other domains in which the information is updated.
Here is the config from vm_idcc_devel:
virsh # dumpxml vm_idcc_devel

Is that too old ?Yeah, that is ~10 years old and I believe that virtio_balloon module is lacking feature that enable QEMU (and subsequently libvirt) report more info. Michal
