For the best experience with the 16.12.1b image, apply these hardware and software optimizations: csr1000vucmk916121bserialqcow2 repack best
: The hypervisor requires the disk image to be named virtioa.qcow2 : mv csr1000v-ucmk9.16.12.1b-serial.qcow2 virtioa.qcow2 .
: If your host CPU usage is too high, try setting the halt_poll_ns=0 parameter on your Linux host to prevent the guest from busy-spinning. : This is a vital step in EVE-NG
: Allocate at least 4GB (4096MB) of RAM and 1 vCPU per instance. Lowering RAM below 3GB often results in boot loops or "Calculating SHA-1 hash" hangs.
To use this image effectively in EVE-NG, you must "repack" it into the correct directory structure and rename it to the format expected by the QEMU hypervisor. : If your host CPU usage is too
: Eliminates the overhead of graphical emulation.
