Hi, I am trying to measure how many UML objects can run on a PC. I guessed that the number depends on tmpfs mounted on /dev/shm. # My hosts provide two tmpfs, mounted on /dev/shm and /lib/init/rw.
My experience was the follows. 1. Run many UML at once on my PC. 2. Some UML crushed, and the UML dumped a message "the host /dev/shm or /tmp mount likely just ran out of space". 3. So, I observed tmpfs (on /dev/shm) and /tmp while booting UML at other time by linux command "df". 4. At that time, after the tmpfs was full (the /tmp was enough space), UML was crushed. The follow is my exercise environment. --- Host os: Ubuntu 8.10 Host memory: 3304620 (measured by free command) Tmpfs mounted on /lib/init/rw: 1652308 tmpfs mounted on /dev/shm: 1652308 UML kernel version: 2.6.28.10 --- Is my guess right? I hope everyone allows my poor English. Thanks. ------------------------------------------------------------------------------ Beautiful is writing same markup.
