I haven't yet had luck getting a pvh domU to launch. I think I'm doing what the documentation calls for, but clearly something is missing. Current bits are up here: https://www.bfccomputing.com/downloads/fedora/xen/f20/ I've got Xen 4.4 booting and a kernel built with PVH support, but when starting a domU with 'pvh=1' I get: xc_dom_parse_image: unsupported feature requested and the domain fails to build. I did verify that BUILD/kernel-foo/.config is getting the entry, and it sure looks like the symbols are in the kernel: [root@librescu xen]# grep -i pvh /boot/config-3.14.4-200.xenpvh.fc20.x86_64 /boot/System.map-3.14.4-200.xenpvh.fc20.x86_64 /boot/config-3.14.4-200.xenpvh.fc20.x86_64:# Linux/x86_64 3.14.4-200.xenpvh.fc20.x86_64 Kernel Configuration /boot/config-3.14.4-200.xenpvh.fc20.x86_64:CONFIG_XEN_PVHVM=y /boot/config-3.14.4-200.xenpvh.fc20.x86_64:CONFIG_XEN_PVH=y /boot/System.map-3.14.4-200.xenpvh.fc20.x86_64:ffffffff81004340 t xen_pvh_set_cr_flags /boot/System.map-3.14.4-200.xenpvh.fc20.x86_64:ffffffff816e04d0 T xen_pvh_secondary_vcpu_init /boot/System.map-3.14.4-200.xenpvh.fc20.x86_64:ffffffff81d2a0a9 t xen_pvh_gnttab_setup /boot/System.map-3.14.4-200.xenpvh.fc20.x86_64:ffffffff81e5fd48 t __initcall_xen_pvh_gnttab_setup1 [root@librescu xen]# uname -r 3.14.4-200.xenpvh.fc20.x86_64 So, I'm not sure what's up. I added "loglvl=all guest_loglvl=all" to grub and can get another reboot in this weekend to see if there's any more info logged. It also looks like I should update my 4.4 tarball to the stable-4.4 branch for non-broken guest shutdowns (but one step at a time). -Bill -- Bill McGonigle, Owner BFC Computing, LLC http://bfccomputing.com/ Telephone: +1.855.SW.LIBRE Email, IM, VOIP: bill@xxxxxxxxxxxxxxxx VCard: http://bfccomputing.com/vcard/bill.vcf Social networks: bill_mcgonigle/bill.mcgonigle -- xen mailing list xen@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/xen
