It was mentioned that VSZ accounts for virtual memory, not used physical RAM. It's not a guaranteed way of identifying excessive RAM usage. Please post /proc/$PID/maps so we can confirm the 900 MB overhead is heap, not just mmaped files or other things. Also please post the full qemu-kvm command-line so it's clear which features are in use. Stefan ^ permalink raw reply [flat|nested] 5+ messages in thread

The biggest single map is 1024 MB of guest RAM (as expected): [40000000] > 7f9777e00000-7f97b7e00000 rw-p 00000000 00:00 0 The following regions are suspicious. They are ~63 MB each. In total they make up around 2709 MB. Notice they are non-readable, non-writeable, non-executable private memory. To track them down you could try reducing the qemu-kvm command-line until they no longer appear. For example, start by disabling spice. Another approach is to use tools like gdb or perf to find who is mapping 63 MB regions.

It's glibc: https://www.ibm.com/developerworks/mydeveloperworks/blogs/kevgrig/entry/linux_glibc_2_10_rhel_6_malloc_may_show_excessive_virtual_memory_usage?lang=en It's nothing to be concerned about. VSS has nothing do with actual memory usage in practice. Regards, Anthony Liguori ^ permalink raw reply [flat|nested] 5+ messages in thread
