Re: [Xen-devel] Unable to Configure Xen Dom 0 in Jeremy's PVOPS Kernel

Dear Pasi,

 

I ran "mount /proc/xen" manually *after* the system booted up, it read /etc/fstab, and mounted /proc/xen successfully!!!

 

Please see the last line of the following "mount" output:

 

/dev/sda2 on / type ext3 (rw,acl,user_xattr)
/proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
debugfs on /sys/kernel/debug type debugfs (rw)
udev on /dev type tmpfs (rw)
devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
/dev/sda3 on /home type ext3 (rw,acl,user_xattr)
fusectl on /sys/fs/fuse/connections type fusectl (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
gvfs-fuse-daemon on /home/enming/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=enming)
none on /proc/xen type xenfs (rw)

 

It is very strange that the system did not mount /proc/xen automatically as indicated in /etc/fstab during bootup.

 

Now I am able to start xend daemon. Please see http://2.bp.blogspot.com/_zzjv8MCM2sk/Smg7pKoH_JI/AAAAAAAAABU/TVkqEEyLzYQ/s1600-h/xen08.jpeg

 

And I can see domain 0 using the "xm list" command already!

 

Any ideas how to make /proc/xen automatically mounted while booting? I thought I already have the xenfs entry in /etc/fstab.

 

/dev/disk/by-id/ata-ST3320620AS_9QF97Q42-part1 swap                 swap       defaults              0 0
/dev/disk/by-id/ata-ST3320620AS_9QF97Q42-part2 /                    ext3       acl,user_xattr        1 1
/dev/disk/by-id/ata-ST3320620AS_9QF97Q42-part3 /home                ext3       acl,user_xattr        1 2
proc                 /proc                proc       defaults              0 0
sysfs                /sys                 sysfs      noauto                0 0
debugfs              /sys/kernel/debug    debugfs    noauto                0 0
devpts               /dev/pts             devpts     mode=0620,gid=5       0 0
none                 /proc/xen            xenfs      defaults              0 0

 

Seems the initscripts did not attempt to mount /proc/xen during system startup.

 

Or should I put "mount /proc/xen" in /etc/rc.local?

 

Thank you!!!

So what does "mount /proc/xen" say ?

And what's your Xen version?
