*SOLVED* /dev/pts support in VE [message #14693]

Hello,

I am running...

door linux-2.6.18 # uname -a
Linux door 2.6.18-028stab035 #1 SMP Thu Jul 5 08:00:10 BST 2007 x86_64 AMD Opteron(tm) Processor 848 AuthenticAMD GNU/Linux

I can see pts's in /dev:-

door linux-2.6.18 # ls /dev/pts*
0  1

However, the same command in the VE returns nothing.

What do I have to do to have pts's in a VE?

Best Regards, Paul.

have you compiled kernel yourself?
what OS is used inside VE?

Yup, Vanilla 2.6.18 patched with patch-ovz028stab035.1-combined.gz, using kernel-2.6.18-x86_64-smp.config.ovz as .config, with a few changes to suit my devices.

As I said, base instance has pts's - Host os is Gentoo 2006.1, template is gentoo-20060317-amd64-stage3.tar.gz.

Best Regards, Paul.

I guess you have to mount /dev/pts inside a VE, i.e. smth like

mount -t devpts devpts /dev/pts

OR if /dev/pts line is there in /etc/fstab just

mount /dev/pts

Probably stage3 doesn't do that for you

Hi Kir,

Sorry for the delay, I have been distracted.

fstab doesn't even exist for the VE, which might explain it. Executing the mount command gives...

colo2 dev # mount -t devpts devpts /dev/pts
colo2 dev # ls /dev/pt*
/dev/ptmx  /dev/ptyp0  /dev/ptyp1  /dev/ptyp2  /dev/ptyp3  /dev/ptyp4  /dev/ptyp5

/dev/pts:
colo2 dev #

so it looks like the mount command works OK - there just aren't any pts's. Any (more) ideas? - and thanks,

Best Regards, Paul.

I guess the problem is now solved -- you just need to make sure this mount executes somewhere during the course of VE booting (i.e. in /sbin/rc sysinit or else). Maybe you need to put the appropriate line in /etc/fstab for it to work.

As I know those /dev/pts/* entries are created dynamically -- ssh sessions and vzctl enter creates/uses these in some cases. Try ssh-ing into VE or use vzctl enter and see if there are some devices appearing.
