Do they require any special repos besides the base ones? I'm trying to build them on a 32-bit centos 5.4 VM on top of vmware server and the build doesn't even start, it fails with:

but uriparser-devel is not in the standard repos:
[root@localhost SPECS]# yum search all | grep uriparser [root@localhost SPECS]#
Is anything here I'm missing?
uriparser-devel is in the EPEL repo. To rebuild it against a specific kernel, use the kversion define like:
rpmbuild -ba --define 'kversion 2.6.18-194.3.1.el5' open-vm-tools- kmod.spec

Hello ,
I use Centos 5.4 , with the redhat version of xen . I need for some guest to change the hardware for the network . So in my xen config i add the model option in the vif line .
When the guest boot , i had the right emulation , but after a reboot , the guest loose the configuration .
Someone can confirm the bug in centos 5.5 ?
Have someone a patch ?
Extract of my config :

So when you first "xm create" it, it's ok, and after you reboot the guest, the NIC model has changed?

It's a very old bug :-( . Cf http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=867

Centos 5.5 use a new version of xen , and i hope than my bug is fixed in it , but before upgrade i want a confirmation .
Did you search Redhat bugzilla?
Yes .

Hi
Is it expected behaviour that a libvirt NAT-based network is faster than a libvirt routed network?
I would guess that the routed network would be the fastest one in all cases, but I'm seeing the opposite in my setup. On a 100mbit internet connection, the routed network tops at 4mbyte/sec, while the nat-based network goes all the way to 10mbyte/sec. I've spend the last 6 hours on trying to figure out the cause of this, changing settings, reinstalling the system, but the problem persists and I can't find the cause of it.
It is a clean and fairly simple setup:
- Clean installation of CentOS 5.5
- Installation of kvm+libvirt+virt-manager+xorg
- iptables service disabled
- 1 public IP for the host (xxx.yyy.zzz.215) on a /32 subnet with
xxx.yyy.zzz.193 as gateway
- 3 public IP for the routed network (xxx.yyy.zzz.251-253) on a /26
subnet with the same gateway as the host
- 1 virtual machine with either the NAT or the routed libvirt
network assigned
I have no networking connection errors or similar, it works perfectly with both the NAT and the routed network, but the routed network is just 2-4 times slower than the NAT one.
Do you have any suggestions of what the problem might be? When I look at the iptables rules generated by libvirt, and the routing table, everything looks fine AFAICT. Traceroute from guest doesn't reveal anything either. Ping times from the two networks are similar, so the main issue seems to be throughput.
Any help or pointers to what I should look at, is highly appreciated... :)
I've copy pasted some of my relevant system configuration into pastebin: http://pastebin.com/jtTrHLqA
