Hi, I'm wondering how to explain following metrics I got from libvirt, regarding memory stats for the two GUESTS running on my host. 1) virDomainGetXMLDesc() shows these values : memmax (1024000.000000) memcurrent(1024000.000000) memmax (2048000.000000) .memcurrent(2048000.000000) 2) As values returned by virDomainMemoryStats(), I got these values : VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON: active_balloon (1024000.000000) active_balloon (2048000.000000) VIR_DOMAIN_MEMORY_STAT_RSS: rss(1194195.312500) rss(2039269.531250 3) By using cgroup counters "memory.usage_in_bytes" for both Guests, I got these values : memusage (1 207 207 031 250) memusage (2 834 503 906 250) How is it possible to have a balloon size equal to memcurrent ? What "memory.usage_in_bytes" stands for (it's the maximum value of the three metrics I got for each GUEST) ? FYI , I use a 1.2.8 libvirt. Thanks. Reagrds, J.P. Ribeauville P: +33.(0).1.47.17.20.49 .
