[KVM_AUTOTEST][PATCH] KSM_overcommit: dynamic reserve calculation (2)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

thanks for nice page about git workflow. I always wanted to try it but never had the time to sit down and learn...

Booth the TMPFS and 0.055 guest_reserve constant are set empirically using various RHEL and Fedora guest/hosts. Smaller hosts can work with smaller (0.045) constant but we didn't want to make the code more complex to exactly fit the limits.

Original changelog:
* NEW: guest_reserve and host_reserve are now calculated based on used memory
* NEW: tmpfs reserve is also evaluated to fit the overhead
* NEW: VM alive check during split_guest()
* FIX: In function split_guest() we used incorrect session
* MOD: Increase number of VNC ports

Best regards,
Lukas
