Hi Jeff,

Were you able to get it tested? We are waiting to deliver the patches to our

  It looks like however you saved the patch file, it was corrupted.
  Looking at your attached patch 3, it split line 9 across 2 lines.
  Your patch also has whitespace differences from the patch I sent.
  
  You also attached 5 patches - Why are you using patch 0?  You should only 
  be applying patches 1-4.  This should not be causing any actual issues, 
  however.
  [Amulya]: First time we applied patches 1 to 4, created VHDX image and 
  deployed to HyperV Server, but we got the same error. Then we took a fresh 
  qemu source and applied patches 0 to 4 and deployed to HyperV and again got 
  the same syntax error.
  
  
  Are you using git for your qemu version?  If so, 'git am' is the preferred 
  method of applying the patches - just save each of the patch emails (the 
  whole email should be fine), and run 'git am' on each file.
  
  [Amulya] : No. We don't have a git repository for our team. Could you 
  please let us know how to apply these patches without git. What is the 
  difference in applying the patch directly and modifying the code directly? 
  Does it have any impact?
  
   
   
   
  Hence, we manually added the patch3 changes and recompiled the qemu. We
  then used the patched qemu-img to convert  our vmdk image to dynamic

  decrease in its size from 50GB to 12GB.
   
  
  Could you tell me the file size of the VMDK image you were converting?
  Is it roughly 12GB as well?

Re: [Qemu-devel] [PATCH 4/4] block: vhdx - set .bdrv_has_zero_init to bdrv_has_zero_init_1

2014-12-12 Thread Lokesha, Amulya
Hi Max,



We applied all the 5 patches from the mail chain I got since the last week. 
Please find attached the patches used by us.

We were unable to apply the patch3 as it failed with the following error



# patch -p1  patch3

patching file block/vhdx.c

patch:  malformed patch at line 17:  error_setg_errno(errp, EINVAL, 
Image size too large; max of 64TB); @@ -1936,7 +1936,9 @@ static QemuOptsList 
vhdx_create_opts = {





Hence, we manually added the patch3 changes and recompiled the qemu. We then 
used the patched qemu-img to convert  our vmdk image to dynamic VHDX format. We 
found that the image created this time had a considerable decrease in its size 
from 50GB to 12GB.

However, when we deployed it into our SCVMM 2012, the import of the VHDX image 
failed with a syntax error as below

Unable to import \\Test.com\Library\VHDs\Test-disk1.vhdx because of a syntax

Please let us know if we missed anything.



Thanks,

 Hi,



 I raised a bug https://bugs.launchpad.net/qemu/+bug/1399191 in the qemu 
 bugzilla and immediately started getting these patch mails. But, I am not 
 seeing any update in the bugzilla site.

 Till now I have got 4 patch mails regarding the issue. Please let me know 
 which patch I should apply. Also let me know where can I get the patch files 
 individually to be downloaded.

Hi Amulya,



Patches 3 and 4 are absolutely necessary for this issue; however, I would 
recommend to simply apply all patches of the series.



In order to download the patches you can simply save the patch emails and apply 
them with git am. If for some reason you don't want to use git, patch -p1 works 
as well.

It looks like however you saved the patch file, it was corrupted.
Looking at your attached patch 3, it split line 9 across 2 lines.
Your patch also has whitespace differences from the patch I sent.

You also attached 5 patches - Why are you using patch 0?  You should
only be applying patches 1-4.  This should not be causing any actual
issues, however.

Are you using git for your qemu version?  If so, 'git am' is the
preferred method of applying the patches - just save each of the patch
emails (the whole email should be fine), and run 'git am' on each
file.

Could you tell me the file size of the VMDK image you were converting?
Is it roughly 12GB as well?

First time we applied patches 1 to 4, created VHDX image and deployed to HyperV 
Server, but we got the same error. Then we took a fresh qemu source and applied 
patches 0 to 4 and deployed to HyperV and again got the same syntax error.

method of applying the patches - just save each of the patch emails (the whole

[Amulya] : No. We don't have a git repository for our team. Could you please 
let us know how to apply these patches without git. What is the difference in 
applying the patch directly and modifying the code directly? Does it have any 
impact?
