Hi, As you can see below there is a bug when you don't use the default virt_ram virt_file_size Even when I give it to the profile add the settings are correctly saved (/var/lib/cobbler/profiles) but when cobbler list you don't see your setting when using koan he also doesn't see the setting my problem is that i don't have 512MB free memory so it fails cobbler profile add --name=fc6test --distro=fc6test --virt-file-size=3 --virt-ram=96 cobbler list defaults kernel options : append devfs=nomount ramdisk_size=16438 lang= vga=788 ksdevice=eth0 distro 1 : fc6test kernel : /boot/vmlinuz-2.6.18-1.2798.fc6xen initrd : /boot/initrd-2.6.18-1.2798.fc6xen.img kernel options : architecture : x86 ks metadata : distro 2 : var_www_cobbler_localmirror_fc6_images_pxeboot kernel : /var/www/cobbler/localmirror/fc6/images/pxeboot/vmlinuz initrd : /var/www/cobbler/localmirror/fc6/images/pxeboot/initrd.img kernel options : architecture : x86 ks metadata : profile 1 : fc6test distro : fc6test kickstart : /etc/cobbler/default.ks kernel options : ks metadata : virt name : fc6test virt file size : virt ram : virt paravirt : profile 2 : var_www_cobbler_localmirror_fc6_images_pxeboot distro : var_www_cobbler_localmirror_fc6_images_pxeboot kickstart : /etc/cobbler/kickstart_fc5.ks kernel options : ks metadata : tree=http://127.0.0.1/localmirror/fc6 virt name : var_www_cobbler_localmirror_fc6_images_pxeboot virt file size : virt ram : virt paravirt : There are no configured System records. koan --virt --profile=fc6test --server=localhost - processing profile: fc6test - fetching configuration for profile: fc6test - url=http://localhost/cobbler/profiles/fc6test - {'kickstart': 'http://127.0.0.1/cobbler/kickstarts/fc6test/ks.cfg', 'name': 'fc6test', 'virt_ram': '', 'virt_paravirt': '', 'kernel_options': 'lang ksdevice=eth0 vga=788 devfs=nomount ramdisk_size=16438', 'virt_name': 'fc6test', 'virt_file_size': '', 'distro': 'fc6test', 'ks_meta': ''} - fetching configuration for distro: fc6test - url=http://localhost/cobbler/distros/fc6test - {'kernel': '/boot/vmlinuz-2.6.18-1.2798.fc6xen', 'ks_meta': '', 'kernel_options': 'lang ksdevice=eth0 vga=788 devfs=nomount ramdisk_size=16438', 'initrd': '/boot/initrd-2.6.18-1.2798.fc6xen.img', 'arch': 'x86', 'name': 'fc6test'} - downloading initrd initrd-2.6.18-1.2798.fc6xen.img to /tmp/initrd-2.6.18-1.2798.fc6xen.img - url=http://localhost/cobbler/images/fc6test/initrd-2.6.18-1.2798.fc6xen.img - downloading kernel vmlinuz-2.6.18-1.2798.fc6xen to /tmp/vmlinuz-2.6.18-1.2798.fc6xen - url=http://localhost/cobbler/images/fc6test/vmlinuz-2.6.18-1.2798.fc6xen - kernel saved = /tmp/vmlinuz-2.6.18-1.2798.fc6xen - initrd saved = /tmp/initrd-2.6.18-1.2798.fc6xen.img - invalid RAM size specified, defaulting to 256 MB - invalid file size specified, defaulting to 1 GB libvir: Xen Daemon error : GET operation failed: No such domain 6 libvir: Xen Daemon error : POST operation failed: (xend.err 'Error creating domain: I need 262144 KiB, but dom0_min_mem is 262144 and shrinking to 262144 KiB would leave only -15940 KiB free.')
