[Xen-devel] Scrubbing free ram

Hi everyone,

I am working on a project whose goal is evaluating
the performance of the vTPM Manager. For this project I am using Xen
4.1, Kernel 2.6.31.13 with Fedora11. I I finished all installation and
configuration parts. Now I need to boot the system with Xen but while
booting, it is freezing at the step "scrubbing free ram". What can be
cause this problem and how can I figure it out? I really appreciate if
you can help me.


Thanks for your time and help.
Best,

RE: [Xen-users] Re: [Xen-devel] Scrubbing free ram

Thank you very much for your concern about my issue. After sending email to
xen-devel, I switch to Debian 5 to install Xen, I do not have any problems but I
am still very curious about the problem. Since I installed Debian now, I just
have this part of my grub.conf entry of Fedora:
title pv_ops dom0-test (2.6.29) with serial console
    root         (hd0,2)
    kernel       /boot/xen-4.0.0-rc6.gz dom0_mem=1024M loglvl=all
guest_loglvl=all sync_console console_to_ring com1=115200,8n1 console=com1
lapic=debug apic_verbosity=debug apic=debug iommu=off
    module       /boot/vmlinuz-2.6.29-xen-r4 ro
root=UUID=e173017f-7b9a-4111-acf7-b9f0d02a8936 console=hvc0 earlyprintk=xen
nomodeset initcall_debug debug loglevel=10
    module       /boot/initrd-2.6.29-xen-r4.img

I also want to ask you something about Debian 5+Xen 4.0 . I booted with Xen in
my Debian installed machine. However there is a problem about the eth0. Xen 4.0
did not recognize my eth0. I do not know what to do about this. Do you have any
idea about this?
Thank you again very much for your time and help.

Please update to 4.0.0 final, or even 4.0.1-rc version.. 
many bugs fixed after 4.0.0-rc6.

Xen doesn''t have drivers for hardware/nics. It''s the Linux
dom0 kernel that has the NIC driver.
Does "lspci -v" list the nic (when booted to Xen dom0)? 

Also please paste your dmesg.

Also is there a specific reason you''re using 2.6.29-xen-r4 (xenlinux)
kernel
instead of the pvops dom0 kernel?

pvops dom0 is the default dom0 kernel in Xen 4.0.0.

Re: [Xen-users] Re: [Xen-devel] Scrubbing free ram

Hello ilish,

Did your network card work with the fedora install ? And if yes, what kernel
version that you use there ?
Could be it isn''t supported yet in the 2.6.29 kernel ?

What does lspci -vk show as your network card ?

Re: [Xen-users] Re: [Xen-devel] Scrubbing free ram

ok so it works fine with exactly the same kernel but booting without xen?
Verifying to see if its build in, could be done by looking for the appropiate
.config file for your kernel version in /boot/
And doing something like

cat .config-2.6.x | grep SKY2


> It works fine actually without booting Xen hypervisor. Actually I have
several sources those explain compiling Xen and kernel, since I am new in this
area I don''t exactly know if compiled this driver or not. I am
wondering if it is possible to check now whether I compiled this driver.

Re: [Xen-users] Re: [Xen-devel] Scrubbing free ram

And if you boot the 2.6.18 kernel you use for xen, but without loading the xen
hypervisor, does the network card work then ?
Probably your 2.6.18 kernelsversion of sky2 doesnt support your newer marvell
yukon network card.

The xen-4.0.0-rc6 is that coming from a debian package ?

I still would recommend you compiling a pvops kernel with the sky2 drivers as
explained in steps on http://wiki.xensource.com/xenwiki/XenParavirtOps
These are recent kernels, and should provide the best hardware support for newer
hardware.

> Actually I with my Debian I am using 2.6.26 kernel verison, however for
Dom0 I am using 2.6.18 as my kenel. Can I use my actual Debian kernel, on which
the network card is working, fir my Dom0? If yes I do need to make some changes
on the config file, is that right?

have several sources those explain compiling Xen and kernel, since I am new in

Do things work if you add no-bootscrub to the Xen command line?

Re: [Xen-devel] Scrubbing free ram

Probably something to do with dom0 building then. I would try a different
dom0 kernel just to see if that works better. But probably there is a bug
here that a developer will need to be able to reproduce to fix.

Re: [Xen-devel] Scrubbing free ram

Some other options: add noreboot to Xen command line and see if anything
else does get printed before reboot. And/or connect a serial line and have
Xen log to serial console and see if any other diagnostic messages are
visible from that.

Re: [Xen-devel] Scrubbing free ram

Dear Pasi,

I have the same problem as ilish had when I installed xen 4.0 on fedora 11
today. I rebooted the Xen. The screen just stopped at "Scrubbing Free

Re: [Xen-devel] Scrubbing free ram

Hello Keir,

Thank you very much for your reply. As you said, I just change my grub.conf
as following. But it also did not work. The screen just stopped when message
"(XEN) Dom0 has maximum 4 VCPUs" was printed, which is just before the
message "Scrubbing Free RAM:". And then system reboot.

title Xen-4.0 (Linux kernel 2.6.31.13)
    root (hd0,10)
    kernel /boot/xen-4.0.gz no-bootscrub dom0_mem=1024M loglvl=all
guest_loglvl=all
    module /boot/vmlinuz-2.6.31.13 root=/dev/sda1 ro nomodeset
    module /boot/initrd-2.6.31.13.img

Thank you. Best wishes.

Re: [Xen-devel] Scrubbing free ram

Hi,

Sorry, I can not get the boot message through XenSerialConsole now. However,
attached are the screenshots of the last part of boot message.
If add "no-bootscrub" on the xen command line, the message is the same
except for the last line, "(XEN) Scrubbing Free RAM:". The grub.conf
is as
following.

 title Xen-4.0 (Linux kernel 2.6.31.13)
    root (hd0,10)
    kernel /boot/xen-4.0.gz dom0_mem=1024M loglvl=all guest_loglvl=all
    module /boot/vmlinuz-2.6.31.13 root=/dev/sda1 ro nomodeset
    module /boot/initrd-2.6.31.13.img

Best wishes.

I wonder if this is somehow related to similar problem I''ve been having
using pv_ops dom0 2.6.32.10 on my AMD hardware.  Finally I was able to 
track down where it showed BUG: soft lockup on the screen.  Nothing 
seems to get rid of this soft lockup problem.  I''ve been trying various
different settings all day.

Try whatever dom0 kernel it is that you were using before the switch to Xen
4.0. It should still work.

Was this kernel boot line the same as the previous kernel you used?
Also, please consult the http://wiki.xensource.com/xenwiki/XenParavirtOps
which Pasi refered to you earlier, and look in the "Are there more
debugging
options I could enable to troubleshoot booting problems?"

I wonder if "earlyprintk=xen" for the pvops dom0 kernel would help
here..
And since you seem to be using a serial console make it "earlyprintk=xen
console=hvc0"

The ''debug'' by itself makes Linux print by majority most of
the
warnings/errors/debugs. etc. So he should definitly use that.

Re: [Xen-devel] Scrubbing free ram

Hi, Konrad,

Thank you for your reply.

I think it is hard to solve the problem of installing xen4.0 on
fedora11_x86-32bit. Because everytime I install xen4.0 and reboot, my screen
stopped at the below messages and did not to print anything.

(XEN) traps.c:2309:d0 Domain attempted WRMSR 000002ff from
00000000:00000c06> to 00000000:00000000.


Now, I change my domain0 OS to fedora11_x86-64bit and I can successfully
install the xen 4.0. However I have another problem. When I running the
command "xend start", I got the error messages:

[root@localhost ~]# xend start
ERROR Internal error: Could not obtain handle on privileged command
interface (2 = No such file or directory)
Traceback (most recent call last):
  File "/usr/sbin/xend", line 36, in <module>

xen.lowlevel.xc.Error: (1, ''Internal error'', ''Could

I googled the problem and found it seems to be a bug, which refered here:
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1436



If I running another command "/etc/init.d/xend start", it can
successfully
start the xend service. But I can not create a PV DomU or HVM DomU. The
error message as following.

1. Error of starting a PV DomU

Right. And if you used the Linux and Xen kernel command line options to
enable more debug option that Pasi and I''ve pointed you to
you would have seen more. They are in
http://wiki.xensource.com/xenwiki/XenParavirtOps under the section
titled "Are there more debugging options I could enable to troubleshoot
booting problems?" where it gives you an example:

xen-4.0.gz dom0_mem=1024M loglvl=all guest_loglvl=all sync_console
console_to_ring com1=115200,8n1 console=com1 lapic=debug apic_verbosity=debug

So you solved your problem by building the 64-bit Dom0. Is your
userspace 64-bit or is it 32-bit? When you say ''change my
domain0'' was
that a re-install of Fedora Core 11?

That one is fairly easy. You don''t have the right
''root'' entry for your
guest (you are missing the right root="/dev/<something,
something>").

It looks to be that you are trying to do ''/dev/sda1'' but since
you
changed your disk=[''...''] entry to have
''xvda'', it should be
''/dev/xvda1''

No idea without cranking up some debug options. Look up
http://wiki.xensource.com/xenwiki/XenParavirtOps at the debug option.

Yes, I have re-install the 64-bit Fedora Core 11. My userspace is 64-bit

I have solved the problem about creating a HVM DomU just by adding
"CONFIG_TUN=m" in the kernel config file and rebuild the linux kernel.

The detail error about creating a hvm domU, which is in the file
/var/log/xen/qemu-dm-WinXP_HVMDomain.log, is listed as below.

[root@localhost xen]# cat qemu-dm-WinXP_HVMDomain.log
domid: 2
warning: could not open /dev/net/tun: no virtual network emulation
Could not initialize device ''tap''
