[uml-user] Problems booting guest filesystem

[Ernie Fontes]

Hi, I am running the linux-2.6.12-skas3-v9-pre7 kernel on my host and the linux-2.6.12-bs9 user-mode-linux kernel. I am trying to get user-mode-linux running so that I can experiment with setting up virtual networks with the aid of projects such as VNUML (http://jungla.dit.upm.es/~vnuml/), netkit (http://www.netkit.org/), and umlazi (http://www.umlazi.org/).  However, all of these projects have problems booting guest filesystems.  In further exploration, I tried to get uml to load the filesystems on the user-mode-linux page (http://user-mode-linux.sourceforge.net/dl-sf.html).  Slackware loads fine, but the red hat 7.2-full filesystem hangs while booting. I am still very new to linux and user-mode-linux, so if you would like to see any other log files, etc., please ask and I’ll try to get them.   Below is the output of booting Redhat 7.2 with uml.   Ernie Fontes   [EMAIL PROTECTED] Desktop]# linux ubd0=~/rh_cow:root_fs.rh-7.2-full.pristine.20020312 Checking for /proc/mm...found Checking for the skas3 patch in the host...found Checking PROT_EXEC mmap in /tmp...OK Linux version 2.6.12-bs9 ([EMAIL PROTECTED]) (gcc version 4.0.1 20050727 (Red Hat 4.0.1-5)) #1 Thu Aug 4 10:09:14 EDT 2005 Built 1 zonelists Kernel command line: ubd0=/root/rh_cow:root_fs.rh-7.2-full.pristine.20020312 root=98:0 PID hash table entries: 256 (order: 8, 4096 bytes) Dentry cache hash table entries: 8192 (order: 3, 32768 bytes) Inode-cache hash table entries: 4096 (order: 2, 16384 bytes) Memory: 28976k available Mount-cache hash table entries: 512 Checking for host processor cmov support...Yes Checking for host processor xmm support...No Checking that ptrace can change system call numbers...OK Checking syscall emulation patch for ptrace...OK Checking advanced syscall emulation patch for ptrace...OK Checking that host ptys support output SIGIO...Yes Checking that host ptys support SIGIO on close...No, enabling workaround Checking for /dev/anon on the host...Not available (open failed with errno 2) NET: Registered protocol family 16 mconsole (version 2) initialized on /root/.uml/ChxGqg/mconsole ubd: Synchronous mode VFS: Disk quotas dquot_6.5.1 Dquot-cache hash table entries: 1024 (order 0, 4096 bytes) devfs: 2004-01-31 Richard Gooch ([EMAIL PROTECTED]) devfs: devfs_debug: 0x0 devfs: boot_options: 0x1 io scheduler noop registered io scheduler anticipatory registered io scheduler deadline registered io scheduler cfq registered NET: Registered protocol family 2 IP: routing cache hash table of 512 buckets, 4Kbytes TCP established hash table entries: 2048 (order: 2, 16384 bytes) TCP bind hash table entries: 2048 (order: 1, 8192 bytes) TCP: Hash tables configured (established 2048 bind 2048) NET: Registered protocol family 1 NET: Registered protocol family 17 Initialized stdio console driver Console initialized on /dev/tty0 Initializing software serial port version 1 Creating "/root/rh_cow" as COW file for "root_fs.rh-7.2-full.pristine.20020312"  /dev/ubd/disc0: unknown partition table VFS: Mounted root (ext2 filesystem) readonly.
