Using a FC6 Guest as Internet gateway, proxy etc
by Philip Rhoades
People,
Now that I can create FC6 Guests running on FC6 quite happily I am
thinking of using a very stripped down, minimal Guest as the Internet
gateway, proxy etc for the host machine such that the Guest has the real
IP address and the host machine is using a typical private IP address eg
192.168.0.10 - is anyone else doing this successfully?
Thanks,
Phil.

Xen vm install
by John Mizell
I am trying to install fedora 6 64 guest on top of a fedora 6 64 host
with xen. I have tried using nfs and ftp. Both methods stall during the
package install and never complete. Is there a work around for this or a
fix on the way?

Re: [Fedora-xen] No success installing Windows XP in fully-virtualized domain
by Rodolfo Martinez
Hi Daniel,
I found this workaround in the list archives... It worked for me.
"I had this problem, too - the solution was re-installing WinXP, and,
when the installer asks you to press 'F6' for addtional drivers, press
'F5' instead. Then select 'Standard PC ...'"

Subject: [Fedora-xen] No success installing Windows XP in fully-virtualized domain
Hi,
I tried installing Windows XP in a fully-virtualized guest domain, using
Fedora Core 6, but had no success.
The installation would never proceed beyond the reboot halfway in the
install process; sometimes even abort earlier.
I tried this both with virt-manager, and with hand-crafted config files,
fiddling with all possible variations of acpi and apic settings.
Using a successfully installed Windows domain appears to be no problem,
though - even with both acpi and apic turned on.
I managed to create a Windows XP domain with the free version of
XenEnterprise without any problems. Is there anything special about the Xen
implementation in this product? I ask, because it struck me when I tried to
install Windows 2000 - which they say they don't support - all went fine,
except that all dialog texts in the installation process were blacked out..
Using it is no option for me, because I want to use the machine both for
various servers and as my desktop machine.
(I also tried Debian Etch, but wasn't successful either...)
Does anyone have suggestions what I could do:
- to be able to give a more meaningful report what goes wrong?
- to create other Windows domains in the future?
The hardware I'm using:
- AMD 64X2 5000+
- Asus M2N-SLI deluxe motherboard (nVidia nForce 5 chipset)
I also upgraded the BIOS to the latest version, just to be sure.

R: [Fedora-xen] Network Problem after todays update
by Cecere, Antonio (EXT)
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...

Oggetto: Re: [Fedora-xen] Network Problem after todays update
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 ..
Sven

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 ?

Simple testing results for Xen and VMX on FC5-test2.
by You, Yongkang
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

Save&Restore VMs
by Cecere, Antonio (EXT)
Hi fedora-list,
>From the terminal I have created a VM, four VM on FC6Xen, because the
virt-manager [0.2.6] has a nice graphic, but the programme it's not
complete.
[root@localhost ~]# xm list

The VMs run perfectly but when I try to save them whith # xm save Dom1
Dom1.chk an error is given on the /usr/lib/xen/bin/xc_save. Restoring
the VMs is impossible.
[root@localhost ~]# xm save test03 test03.chk

Save a domain state to restore later.
Do you have any idea???

Installing Xen in a low memory environment
by Formoso, Travis
Hi guys,
I am trying to set up Xen with a machine that has only 256 MB. I set up
a NFS share and it does go to the install part, however it stops usually
between 10-20% of the install. I was wondering if I could do anything to
set this up with such low memory.
Thanks

Re: many many error messages in kernel log : 4gb seg fixup, process acroread

Thanks for the suggestions. I ended up rebooting into the non-xen
kernel (2.6.18-1.2869), and these messages disappeared.
