I am testing several Operating System Streaming products to streams
virtual desktops.
They always requires pxe boot but xen seems to have a pxe which is not
suitable.
I got the same problem with kqemu and kvm and I solved it using gpxe.
With xen I tried to chainloading gpxe (following gpxe wiki) but
hvmloader fails to load it (memory problem?).
Any workaround about this problem or patch in future releases ?
Many Thanks & Regards
Igna

I make heavy use of this and it works fine - net-booting your dom0 and domus is really cool ;) I think your problem is your bridge.

Re: [Xen-users] xen hvmloader gpxe
I know pxe under xen and kvm is good for linux domu.
But have you ever tried for windows domu using neoware image manager
streaming or vhdsoft os streaming ? They requires an upgraded pxe.
I am sure kvm does not work if you don''t add gpxe support to it.
I am sure Xenserver (from Citrix) does not work (it works only with
Citrix Provisioning).

But in your case the systems are vms. If you put your vm-images on a shared-storage (nfs, iscsi, aoe, nbd or whatever) its the same in my eyes. Or don''t i get you right? Why do you want/need netbooting windows-vms? Have a look at @http://openqrm.com/storage-cluster.png As you can see all DATA is in my storage-cluster and the dom0s have NO local-disks, since they do netbooting. All vms resist in the storage-cluster too....> They requires an upgraded pxe. > I am sure kvm does not work if you don''t add gpxe support to it. > I am sure Xenserver (from Citrix) does not work (it works only with > Citrix Provisioning).You could also have a look at openqrm, which could be interesting to you, since it supports many hypervisors (vmware server, esx, xen, citrix xen, kvm, v-server,..), provides HA, integrated Monitoring, incl. Storage-Management (nfs, iscsi, aoe, lvm, local-disks), providing cloud-computing and finally its GPL. http://www.openqrm.com The new release adds some new features - especially the xen and kvm-part has been enhanced> Regards > IgnaRegards, Thomas _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] xen hvmloader gpxe
I.
I think it''s very important maintaing windows diskless guests.
If we have lots windows guests could be very important maintan them
using a single image.
Windows diskless is very different vs linux diskless.
Using VhdSoft or neoware image manager, you can make a single image
for all windows guests (for example a 8GB image).
Each windows guest which boots from network work on the single image
and store a differencing cache image on the storage.
Firstly you can avoid to duplicate 8GB for each client.
Secondly you can handle updates on a single image rather than on each guest.
Thirdly you can decide to setup each image in administrator mode (to
add patch or software), volatile mode (each modification is lost at
next reboot), persistentg mode (write cache is not lost at next reboot).
This technology could be used for physical PC, but it is very very
usefull for virtual guests because virtual guests have the same
hardware (so you need a single image).
In other words I would be to make a Virtual Desktop Infrastructure
saving money for storage and maintenance.
Are you agree ?
