These two patches fix potential issues. Best to get them tested over
Christmas and New Year.
v2v: Swap over the output and conversion stages
In old virt-v2v, we did (approximately, since the steps were not as
clear):
Input -> Convert -> Output -> Copy -> Finalize
After modularizing virt-v2v we changed this to:
Input -> Output -> Convert -> Copy -> Finalize
However this has a (sort of) problem. For -o rhv-upload when we start
the nbdkit rhv-upload-plugin machinery, it obtains a time-limited
ticket from imageio. This ticket could expire if the conversion step
takes longer than a certain time (60 seconds by default, may be
increased in a future version of oVirt).
I believe this is really a problem in imageio or that the
rhv-upload-plugin should really renew this ticket automatically, but
it does not, instead failing. (The ticket *is* renewed automatically
whenever a request is sent to imageio, but in this case no requests
are being sent).
Anyway the easiest thing is to switch the ordering back to how it was
in old virt-v2v (at top). It doesn't make a difference for any other
output modes.

v2v: Remove nbdcopy --request-size=4M flag
This was added when we were setting the cow-block-size to 1M. However
since commit 351d61f768 ("input: -it vddk: Reduce cow-block-size to 4K")
we stopped doing that so this is no longer needed.

Subject: [PATCH] RHEL: v2v: Disable the --qemu-boot / -oo qemu-boot option
|
||
(RHBZ#1147313).
|
||
|
||
This cannot work because there is no Gtk or SDL output mode
|
||
in RHEL's qemu-kvm.
|
||
|
||
In addition you will have to edit the -display option in the
|
||
qemu script.
