Hi everybody, Attracted by the puppies, I'm trying to run lhype. The patch applies cleanly to 2.6.20-rc2, my .config is in accord with lhype.txt, but when I try to launch an instance, I get this: $ sudo drivers/lhype/lhype_add 64m 0 vmlinux --tunnet=192.168.19.1 --block=linux.img root=/dev/lhba lhype_add: Failed to get DMA buffer from 0xb7fff008: No such file or directory lhype_add: network: no dma buffer!: No such file or directory lhype_add: Running guest failed: No such file or directory When I subsequently retry, I get the same, but third...

...0 just started playing with lguest - patching, compiling and booting the host-kernel goes ok - compiling lguest is ok as well after hardcodeing SIOCBRADDIF - but on the first boot attempt of a guest linux I get: root@darkstar:/usr/src/linux-2.6.21# Documentation/lguest/lguest 64m vmlinux --tunnet=192.168.2.1 --block=../root_fs root=/dev/lgba lguest: unhandled trap 6 at 0xc0117903 (0x0) this should be in "c01178db T reserve_top_address" - any idea what could be wrong ? thx ! hofrat

Hi! Bored by previous lhype success, I tried to boot a debootstrapped debian over nfsroot, and lo, this almost works! Commandline: # drivers/lhype/lhype_add 256m 0 ./vmlinux --tunnet=192.168.1.20 root=/dev/root nfsroot=/home/ahu/lhype-root ip=192.168.1.21:192.168.1.20:192.168.1.20 This with lhype.patch current as of this message and 2.9.20-rc4. The boot process stops after: Starting periodic command scheduler: crond. Trying to use the console yields: lhype_add: Failed to ge...

Hi, I am doing working on enabling Transcendent Memory(OLS '09) support on lguest. For the same, I need ballooning support for lguest. Is there an implmentation of Virtio Balloon driver, that I can use for my purpose? Could someone give me an insight, as to how to go about, for implementing this myself, incase I dont find this patch... Thankyou. -- Gaurav Kukreja +91 997 030 1257

Hi all, These are the patches I'm planning to submit for 2.6.24. Comments gratefully accepted. Along with the usual cleanups and improvements are Jes' de-i386-ification patches, and a new "virtio" mechanism designed to be shared with KVM (and hopefully other hypervisors). Cheers, Rusty.
