660	Cloning Debian Etch guest breaks networking	gnuser		[[BR]]\r\nSee also ticket #645 which says that taking a snapshot breaks networking.\r\n\r\nOn a Kubuntu Feisty host using VirtualBox 1.5 (and 1.4 before with the same result) I created a Debian Etch guest. Then I cloned the disk and used it to create a new virtual machine, but networking fails in the new machine (eth0 just won't come up).\r\n\r\nOn the original machine, starting networking reports, among other stuff, that eth0 is up at 100MB, Full-Duplex.\r\n\r\nOn the cloned machine it just says:\r\n\r\nConfiguring network interfaces...done.\r\n\r\nand all I have is lo. If I try ifup eth0, I get:\r\n\r\n[boilerplate omitted][[BR]]\r\nSIOCSIFADDR: No such device[[BR]]\r\neth0: ERROR while getting interface flags: No such device[[BR]]\r\neth0: ERROR while getting interface flags: No such device[[BR]]\r\nBind socket to interface: No such device[[BR]]\r\nFailed to bring up eth0.[[BR]]\r\n\r\nI've tried this numerous times, starting from scratch. The same thing happens whether I use NAT or bridging.\r\n\r\nThings I've tried that have failed to solve the problem:\r\n\r\n * Rebooting the guest.\r\n * Power-cycling the guest.\r\n * modprobe -r pcnet32 ; modprobe pcnet32\r\n * Not installing guest additions\r\n * Installing guest additions.\r\n * Not installing anything beyond the minimum Debian system.\r\n\r\nHaven't tried it with any Guest other than Debian Etch.\r\n	defect	reopened	major	other	VirtualBox 1.5.0				other	other
