This attempts to implement the idea proposed in https://www.redhat.com/archives/libguestfs/2010-April/msg00087.html The idea is that an externally managed QEMU (manual, or via libvirt) can boot the appliance kernel/initrd. libguestfs can then be just told of the UNIX domain socket associated with the guest daemon. An example based on guestfish. 1. Step one, find the appliance kernel/initrd

Here are two patches that let xm create, save and restore extract and preserve elfnotes read by the domain builder. This is handy for a few things. In particular, I''d like it so that xm can decide whether or not guest domains support fast resume (if save fails, or for checkpointing). _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

Hi all! It's my first message on this ML. I just installed Fedora Core and I had a small problem... kernel + initrd do not fit in a 1.44 disks... I looked at documentation and at code (kernel.inc) and I saw that syslinux - load kernel - load initrd - boot kernel So perhaps a small workaround for above problem should be to add a configuration to initrd (ie initrd=@initrd.img) to just ask to

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
