Fedora xen - Jan 2006 - Simple testing results for Xen and VMX on FC5-test2.

Hi all,

I have done a simple checking for Xen and VMX on FC5-test2. Basically, I can
create VMX on FC5-test2 IA32. But FC5-test2 IA32e (x86-64) doesn''t
provide Xen and Xen0 kernel, so didn''t do Xen and VMX testing for it.

Beside of testing Xen and VMX, I also found some issues about installation,
which I have updated the bug #179078 as a NB. The following is the testing
results only for Xen and VMX.
========================1. *** IA32E hasn''t RPMS about Xen hypervisor
and Xen0/XenU kernels. __FAIL__

2. *** In order to boot up IA32 Xen0, I have to add pci=noacpi as the boot 
parameters of Xen0 kernel, or system will hang when initial PCI. I
don''t know if it is only related to my Machine. __FAIL__

3. After install IA32 Xen RPMs, I can see /boot/grub/grub.conf has been changed 
with Xen kernels.   __PASS__

4. *** /usr/lib/xen/boot/vmxloader isn''t in the RPM package, so VMX
Guest
couldn''t be created. I suspected build system hasn''t bcc, it
is from DEV86
package.  __FAIL__

5. After copy a useable vmxloader to the destination, IA32 VMX Guest can be 
created successfully!  __PASS__ 

6. VMX has good network connection and Xwindows started.   __PASS__

7. XenU can be created and works well.    __PASS__

8. Couldn''t get Xen Changeset by "xm info" or "xm
dmesg".

9. The new kernel names of Xen/Xen0/XenU seemed a little confused. E.g. the Xen0
name is like vmlinuz-2.6.15-1.29_FC5hypervisor. I thought hypervisor is for
Xen.gz. Xen0 is the Service OS.
=========================
Any comments please let me know. But I will have 8 days holiday from tomorrow,
so emails reply might be slow and occasional.

[FYI] We are planning to do more testing for FC5-test3.

Best Regards,
Yongkang (Kangkang) 永康

Getting x86_64 building involved a couple of chicken sacrifices I think.
Stephen was making good progress yesterday, though, so x86_64 will
hopefully show up for test3.

Please file a bug including some actual details about your hardware
instead of just vague statements like this.

Although it would be great if someone would actually port this stuff to
not use ancient, barely maintained toolchains and/or the approach of
actually distributing the firmware in the repository (as done by Bochs,
which is the upstream for this stuff), I went ahead and got dev86 to
build on x86_64 so that vmxloader is in later xen packages.

The kernel-xen-hypervisor package includes both the Xen hypervisor and
the dom0 kernel as these two are tightly intertwined.

It''s coming.  I hope.  The upstream x86_64 stuff from linux-2.6-merge
doesn''t actually compile at the moment (though that''s easy to
fix), and
once compiled it fails in different, compiler-dependent ways on some of
my hardware.  I''ve got a minimally stable boot now on a different box,
but the upstream base in this case is proving hard to work with.

It''s certainly hardware-dependent, but you''re not the only
person
reporting the need for such options.  Please open a bugzilla so that we
can track this one properly, as we''d really like to automate such
options as much as possible for the main release.

One thing that would be worth knowing is whether the main, non-xen
rawhide SMP kernel boots on this box.  The UP kernel disables a bunch of
advanced hardware enablement for compatibility purposes, but the SMP one
should match Xen as closely as possible.

Not sure how easy that would be to add, since we don''t build it out of
Mercurial directly but rather out of a tarballed copy from the CVS build
system.  I''m being careful to add the changeset info to the changelog
in
the rpm, though.

Thanks,
 Stephen

Hi , 

i did an update today from kernel-xen-2.6.18-1.2869.fc6 to 
kernel-xen-2.6.19-1.2895.fc6 and from xen-3.0.3-1.fc6 to xen-3.0.3-3.fc6 .
the upgrade itself went fine, and all on dom_0 works as expected.
But i have now trouble with my guetsts Network. All guests are connecting 
to the outside world over NAT.
i can ssh between all guests as well as between dom_0 and all guests.
i can ping each box outside the dom_0 (my dns server for insteance) but i 
can''t ssh or ftp to any box outside my internal dom_0 network, it
always
timed out.
looking at a tcp dump it marks the frames i send from the guests as 
Checksum Errors.

any ideas ? should i open a bugzilla entry for this ?

Sven

sorry, there was a small typo in my mail, i upgraded from 
kernel-xen-2.6.18-1.2868.fc6 to  kernel-xen-2.6.19-1.2895.fc6 not from 
-1.2869 ..
btw. going back to kernel .2868 fixes it, so there must be a bug added 
between .2868 and .2895 i will test with .2869 later today ..

Hi Sven,

I should also update the kernel, but I''m waiting for the 2.6.20 that
should be released in no time. I have 4 domains in 2.6.18-1.2798.fc6xen and
xen-3.0.3, and they ping between them but I can''t open an ftp transfer,
though I can ping to the outside. Try to make a traceroute<IP> and see
what ride they make. Let me know...
