When I do the mentioned procedure and re-start the guest, all these changes go away
automatically. Looks like Xen "wipes them out". I tried to set these file rights to read only
but since Xen properly runs from root only, it probably chmod on those files and again wipes
out the changes. My guess is that if Xen sees that some argument is not valid due to some
reason (may be absence of mentioned driver or something), it rejects it and changes it to some
default?
Were you able to persist and utilize these changed values?

Dear,
The Guest HVM (fully virt) emulate drivers for NIC's of qemu the options are:
ne2k_isa, ne2k_pci, rtl8139, and
smc91c111.
Model: Specified using model=variable, where variable is one of the specific types of network
cards emulated by QEMU. This option is therefore only useful if you are using ioemu as the type
of network driver you are using. Valid values are lance, ne2k_isa, ne2k_pci, rtl8139, and
smc91c111. The default value is ne2k_pci if you are using QEMU (i.e., ioemu) network drivers
For emulate 1Gpbs use gplpv in http://wiki.xensource.com/xenwiki/XenWindowsGplPv/Installing
Att,

I know in Xen3.0, which comes with FC8, supports at most 100Mbps
in guest if setup is fully virtualized.
The virtual NIC doesn't limit its speed to 100Mb. It reports that to the guest OS because it has to report _something_ but it doesn't throttle back to 100Mb. The only way to find out the actual transfer speed is to measure it -- what you actually get depends on a variety of factors, but not the emulated link speed.
