The problem is: -kernel/-initrd are slow, but we could have a tool that takes kernel image + initrd image + kernel command-line as input, and would generate a small disk image that would boot the provided kernel/initrd images (using the provided kernel command-line) faster than when using -kernel/-initrd. But anyway, it looks like our problem is somewhere else. A 86KB kernel from kvm-unit-tests boots instantly, but for some reason QEMU is taking 15 seconds to boot our 11KB kernel. -- Eduardo _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
