Hi Adam,

Thanks for your hint!

Hm, tried adding more memory to the VM?

Perhaps other users might experienced the same issue:

L4x: Main thread running, waiting... L4x: Memory size: 64MB L4x: Setting superpages for main memory l4x_setup_memory: Can't get main memory of 65536kiB! Please try to add more memory to the VM. MOE[mem_alloc]: quota: limit=-1 Byte, used=9646080 Byte MOE[mem_alloc]: global: avail=52121376 Byte MOE[mem_alloc]: free list (start address/size): MOE[mem_alloc]: 0x210e0 - 0x213ff (800 Byte) MOE[mem_alloc]: 0x273400 - 0x273fff (3 kB) MOE[mem_alloc]: 0x370000 - 0x3fffff (576 kB) MOE[mem_alloc]: 0xba6000 - 0x18aafff (13 MB) MOE[mem_alloc]: 0x541a000 - 0x7838fff (36 MB) Terminating L4Linux.

so I simply added "Please try to add more memory to the VM."

then users might realized that using qemu-system-x86_64 -m 1024M to launch L4Linux-mag-x86, and L4Linux is able to run happily :) https://pbs.twimg.com/media/DB3YY0zVwAA9CM9.png sorry for posting screenshots on Twitter but I am so happy! so excited! and my sincere thank goes to you and Jean! you are teaching me patiently and carefully :)
