in case of cloud / virtualization i wonder what is the state of "zram" in the Fedora Kernel, zswap is available and can be enabled with "zswap.enabled=1" as boot paran
but zswap is more for a overcommited host to avoid disk paging
zram IMHO would be interesting for the guest systems and both combined may lead to run *a lot* of more virtual machines on the same host ____________________________________________________________
[root@srv-rhsoft:~]$ cat /boot/config-3.13.6-200.fc20.x86_64 | grep -i zswap CONFIG_ZSWAP=y
[root@srv-rhsoft:~]$ cat /boot/config-3.13.6-200.fc20.x86_64 | grep -i zram [root@srv-rhsoft:~]$ locate zram /usr/src/kernels/3.13.6-200.fc20.x86_64/drivers/staging/zram /usr/src/kernels/3.13.6-200.fc20.x86_64/drivers/staging/zram/Kconfig /usr/src/kernels/3.13.6-200.fc20.x86_64/drivers/staging/zram/Makefile

I enabled zram in rawhide at the end of January. It was done for bug 1058072 because zram finally moved out of staging with the upcoming 3.14 kernel release.
Fedora release branches will get this enabled when they rebase to 3.14.
