Re: [Xen-users] eddited: Serial console does not set correctly

[tutu sky <ooohooo_u@xxxxxxxxxxx>]

Hi.
after making a serial port in vmware and try monitor by it through puTTy in 
windows host, I'm trying to set a serial console for monitoring Xen and dom0 
(which are installed on vmware too) according to this link: 
http://wiki.xenproject.org/wiki/XenSerialConsole
this is some relevant lines of my /etc/default/grub:

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=60
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_XEN="loglvl=all guest_loglvl=all com1=115200,8n1,0x3e8,5 
console=com1,vga"
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX="find_preseed=/preseed.cfg auto noprompt priority=critical 
locale=en_US console=hvc0 earlyprintk=xen"
...
GRUB_TERMINAL="console serial"
GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=1 --word=8 --parity=no 
--stop=1"

1) but when starting virtual machine while it is connected to puTTy, i get the 
followings on screen and then start lighting caps lock and scroll lock on 
keyboard (actually a sign of kernel panic):

error: serial port 'com1' isn't found.
error: terminal 'serial' isn't found.
error: terminal 'serial' isn't found.
error: no video mode activated.

2) but sometimes these errors will be passed and grub page comes up with a 
serial black appearance! it lets me select, when choosing xen goes into 
hypervisor and start login in GUI (nothing happen in puTTy), but if i choose 
ubuntu from list, just a black page comes up with that lightning.

when starting VM, randomly one of the (1) or (2) scenarios will happen!

for troubleshooting look at this link: 
https://www.ndchost.com/wiki/vps/xen-console-no-login
and lots of others too. i did as they suggested, even add the hvc0.conf file, 
but nothing has changed.
there is some addresses which i browsed:
http://www.gossamer-threads.com/lists/xen/users/258728
https://help.ubuntu.com/community/SerialConsoleHowto
https://wiki.archlinux.org/index.php/working_with_the_serial_console

is there some one to give me a clue? i really need to set this because of some 
development purposes.

(I choose vmware because it seems powerful enough to make a serial port with 
and also actual serial port usage is not possible for me, there is not another 
PC)
Thanks and regards.
