[Qemu-devel] qcow2 snapshot + resize

Hi, In our production environment, we need to extend a qcow2 image with snapshots in it. This feature, however, is not implemented yet. So I want to ask, if this feature is under active development? How can I help with this feature? It seems that, this feature is not too difficult as long

[Qemu-devel] [PATCH] Make rtl8139 network interface card compatible with Mac OS 10.4

This patch solves the few problems that needed to be solved in order for a Mac OS 10.4 guest to use the rtl8139 nic. The pci_dma_read() function would only return zero when a MemoryRegion object was not enabled. Enabling the object makes the pci_dma_read() function work correctly. The Linux
