Running xen-4.1.1 with linux-3.0.0-rc5. I have a kernel that boots on bare metal that I thought should boot as a domU. This is the command: xl create vm1 Here are the first few lines of vm1's config file: # Kernel image file. kernel = "/boot/vmlinuz-2.6.35.6-45.fc14.i686" # Optional ramdisk. ramdisk = "/boot/initramfs-2.6.35.6-45.fc14.i686.img" Here is the error message: Parsing config file vm1 xc: error: elf_xen_note_check: ERROR: Will only load images built for the generic loader or Linux images: Invalid kernel libxl: error: libxl_dom.c:196:libxl__build_pv xc_dom_parse_image failed: Success cannot (re-)build domain: -3 I've seen a lot of the same errors on google but not for xen-4 and xl. Any helpers out there? TIA, Mike Wright ^ permalink raw reply [flat|nested] 4+ messages in thread

I downloaded kernel-PAE-2.6.35.6-45.fc14.i686.rpm from http://rpm.pbone.net/index.php3/stat/4/idpl/15471895/dir/fedora_14/com/kernel-PAE-2.6.35.6-45.fc14.i686.rpm.html (actually ftp://ftp.sunet.se/pub/Linux/distributions/fedora/linux/releases/14/Everything/i386/os/Packages/kernel-PAE-2.6.35.6-45.fc14.i686.rpm ) which contained /boot/vmlinuz-2.6.35.6-45.fc14.i686.PAE with md5sum 09b04a528e1cb4939abb05c739b360e6 and it booted OK for me (until it failed due to lack of a ramdisk).

Thanks for replying, Ian. Turns out I'd messed up in a couple of places. I'd used sda for my targets instead of xvda and no 'root =' in the vm's config. In the vm's /etc/fstab I hadn't adjusted / and /swap to /dev/xvda?, nor had I commented out /boot.
