I have installed an Ubuntu 8.10 PV guest directly from a CD image without going through an HV install first (except to create the CD image). Once the CD image is created, installs seem quick and clean. On AMD, but not Intel. Help?? This is based on Nevada build 101a. (1) Create a suitable CD image I took the standard ubuntu-8.10-server-amd64.iso image and modified it using uck scripts (http://uck.sf.net). The changes are to include the xen drivers in the initrd image and to add /etc/event.d/hvc0 to start a getty for the console. (I did this in an Ubuntu 8.10 HV guest.) (2) Modify /usr/lib/python2.4/vendor-packages/virtinst/OSDistro.py Add a hack to allow it to find the Ubuntu kernel and initrd files, and to extract and unzip the kernel. (3) Modify usr/lib/xen/bin/pygrub Add a hack extract and unzip the kernel so that it can be loaded. (4) Modify usr/lib/fs/ext2fs/fsimage.so Update to allow it to read ext2/3 partitions with a non-standard inode size. (Apply the diffs in solaris/grub bug 6762035 to the xvm-gate.) I''ve attached the customization script and these changes.... Then virt-install from the new image ... virt-install --name=ubuntu1 --paravirt --ram=1024 \ --file=/files/xvm_images/ubuntu1 --file-size=20 \ --location=/files/iso/ubuntu-8.10-server-amd64-pv.iso \ --nographics and select /dev/xvdb as the cdrom device during the install. The install works for me on two Opteron systems (one with AMD-V, one without), but fails on two Core 2 Duo systems. Is PV supported on intel? Any idea why? xend.log shows "Domain has shutdown: name=ubuntu1 id=18 reason=..." when it works (amd) and "Domain has crashed: name=ubuntu2 id=18..." when it doesn''t (intel). Copying a disk image from a working system (amd) to a non-working system (intel) still shows "Domain has crashed" (and tr) in the xend.log. Fred -- This message posted from opensolaris.org
