Re: [Xen-users] Does Xen 3.3 support giga bit network in the guest? 
| 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,

 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.
