[Qemu-devel] initrd not working
Hi, I run qemu-0.8.2 on Kubuntu, and I would like to test an initramfs by booting the kernel with qemu. However, I'm having problems with the initrd. The kernel reports bad gzip magic numbers when checking the initramfs, both with a compressed ext2 filesystem image and with a compressed cpio archive.

[Qemu-devel] kernel panic when using kqemu
Hi, I am using kqemu 1.3.0-pre9 and qemu 0.8.2 on Ubuntu Edgy, kernel 2.6.17-generic. I run into kernel panic in the guest when launching qemu -kernel-kqemu. Some problems found on the net: http://haiku-os.org/trac/ticket/748 http://qemu-forum.ipi.fi/viewtopic.php?p=5011sid=494a2df12b48a1e8fdca8ae0e7bfb752 http://qemu-forum.ipi.fi/viewtopic.php?p=6874sid=494a2df12b48a1e8fdca8ae0e7bfb752 They seem to be the same problem as me, but I don't know how to solve mine. Here are some screenshot: http://www.asso-polyvalente.fr/workspaces/members/mihamina/public/kqemu-debian/ http://www.asso-polyvalente.fr/workspaces/members/mihamina/public/kqemu-fedora/ (the image is larger here: http://www.asso-polyvalente.fr/workspaces/members/mihamina/public , or just save the imageon your computer then see it real size) How to workarroud? ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
