Hi Ian/Stefano, So, I''m back to using pfn space from maxphysaddr below. Stefano, you suggested ballooning, but that would be just too slow. There are lot of pages to be mapped, 4k at a time during guest creation, and I am afraid ballooning and hypercalls to populate EPT will be pretty slow. OTOH, there is tons of address space available between max-physaddr and max pfn in dom0. Stefano,

Hi. I'm attempting to setup a box here to be a file-server for all my data. I'm attempting to resize an ext3 partition to demonstrate this capability to myself before fully committing to this system as the primary data storage. I'm having some problems resizing an ext3 filesystem after I've resized the underlying logical volume. Following the ext3 resize, fsck spits out lots

This patch series implements two optimizations: 1) transfer pages in chuncks between the guest and host; 2) transfer the guest unused pages to the host so that they can be skipped to migrate in live migration. Please read each patch commit log for details. Changes: v7->v8: 1) Use only one chunk format, instead of two. 2) re-write the virtio-balloon implementation patch. 3) commit changes 4)
