Bug 696779

How does the UI for this work in RHEV-M? Is the server/desktop determination made strictly based on the OS selected, or can the user select?

there's a button to create a new desktop or server. the OS is selected afterwards.

In that case I don't think we can base the selection strictly on detected OS. I think a command-line option would make sense here.

What would be a useful default if the user doesn't specify a type? Options I can think of are:

* Server
* Desktop
* Dependent on OS type
* Set per-site in the config file

I would extend the capability tag options in virt-v2v.conf, adding for example

vmtype=
the type of vm in term of capabilities
with possible values desktop, server, both

vmtypedef=
the default vmtype if not specified inside the virt-v2v command

A rh el 6 could contain
<capability os='linux' distro='rhel' major='6' name='virtio' vmtype='both' vmtypedef='server'/>

For w2k3:
<capability os='windows' major='5' minor='2' arch='i386' vmtype='server'>

For Wxp:
<capability os='windows' major='5' minor='1' arch='i386' vmtype='desktop'>

And then in virt-v2v a "-cap" option fro example

So if 
1) for an xp vm you run
virt-v2v -cap server ....
you will get an error and without the -cap you will get a desktop vm

2) for a w2k3 vm if you run
virt-v2v -cap desktop ...
you will get an error and without the -cap you will get a server vm

3) for a rh el 6 vm if you run
a) virt-v2v -cap desktop ...
you will get a desktop vm

b)  virt-v2v ... (without any -cap option)
you will get a server

AFAIK in VMware View, if it can serve as a reference for desktops, you can deploy only windws xp, windows vista and windows 7 systems. 
You cannot simply create w2k3 based desktop pools...
Probably you can create a w2k3 vm in vsphere, install on it the View client piece with its enhanced rdp protocol and broker related things and then manage it from within View, but to create a pool you probably have to create many w2k3 and group them manually in a pool... not OOTB anyway

just my 2eurocent...

BTW: In my opinion it is a sort of ambiguity that the key "name=virtio" appears for linux in "capability" tag, while for windows in "app" tag (with the "path" sub-tag).
Probably it could be changed to be consistent across archs...

Verified the bug with:
virt-v2v-0.8.6-1.el6.x86_64
libguestfs-1.16.2-1.el6.x86_64
libvirt-0.9.9-2.el6.x86_64
rhevm:ic154.1

Steps:
Run man virt-v2v,you can see parameter --vmtype has been added.
#man virt-v2v
  --vmtype type
           Specify the type of guest which will be created on a RHEV target. Options are desktop or server.

1.Use --vmtype to set vm type as desktop.
# virt-v2v  -ic qemu+ssh://10.66.72.122/system -o rhev -os 10.66.90.115:/vol/v2v_manual/nfs_export -n rhevm kvm-rhel6.1-x86_64 --vmtype desktop
kvm-rhel6.1-x86_64.img: 100% [====================================================================================]D 0h02m12s
virt-v2v: kvm-rhel6.1-x86_64 configured with virtio drivers.
2.After conversion,checked the VmType in ovf file:
<VmType>0</VmType>
3.Import the guest to rhevm,it displays as desktop.

Also use --vmtype to set vm type as server.

Cause
The customer is converting a guest to run on RHEV. The guest is a Desktop-type workload.

Consequence
The virt-v2v tool unconditionally marks all converted guests as a Server-type workload. This causes them to be displayed differently in RHEV-M.

Fix
virt-v2v has a new command line option, --vmtype, which will force the conversion process to mark the newly created RHEV VM as either Desktop or Server. If --vmtype is omitted, virt-v2v guesses the type based on the guest operating system as follows:

Windows XP, Vista, 7: Desktop
Windows 2003, 2008: Server
RHEL ES, AS, Server, 2.1: Server
RHEL WS, Desktop, Client: Desktop
Fedora: Desktop
Linux (except RHEL and Fedora): Server

Result
The user can choose either Desktop or Server during the conversion process. If they don't choose explicitly, the result will be either Desktop or Server as defined above.
