That worked! Thanks for the help.
Now I'm tweaking my old code and just replacing my guestfs_mount()
call with a hard-coded "guestfs_mount(g, "/dev/sda",'/");
Next task is to review my registry changes and see if those registries
even exist in Win95.
What this code does is open the image, tweaks some registry settings
to use some "generic" drivers and uploads those drivers. With the
goal of running the VM without resulting in a BSOD. But I might just try
and remove all the "tweaking" and see if a Virtual Box VM can just boot
up the image. Might get lucky.
Besides - I doubt those drivers are Win95 compatible.
I'll let you know how it goes.

virt-v2v - Unable to authenticate to vCenter as DOMAIN\user
by Ben Hooper
Hi,
I am encountering an issue with virt-v2v where I need to authenticate to the vCenter as DOMAIN\user.
I have tried the following with the resulting errors:
1. 'virt-v2v -v -x -ic 'vpx://vcenter/Datacenter/cluster_name/esx_server?no_verify=1' vm_name -o local -of raw -os /tmp'
- prompted for username password
- entered 'DOMAIN\User' as username
- successfully retrieves libvirt xml
- errors with 'virt-v2v: error: vcenter: incorrect username or password.'
2. virt-v2v -v -x -ic 'vpx://DOMAIN\user@vcenter/Datacenter/cluster_name/esx_server?no_verify=1' vm_name -o local -of raw -os /tmp
- errors immediately with virt-v2v: error: could not parse '-ic
vpx://DOMAIN\user@vcenter/Datacenter/cluster_name/esx_server?no_verify=1'.
Original error message was: parse_uri: unable to parse URI
What is the correct syntax for entering the authenticating user as 'DOMAIN\user' for virt-v2v?
Thanks,
Ben.

Communication between Host and Guest
by Priyanka Naik
We wanted to migrate the process from host machine to guest machine using
virtio serial. We have already completed with dumping and restoring
processes. We wanted to transfer those dumped files to guest so that they
could be restored back, using virtio serial. I found many stuff related to
virtio serial but couldn't get the code for transferring files. Can you
provide us with the links which could lead us to our way?

The appliance kernel couldn't find any partitions at all on the disk.
Is it a raw format disk image, or some other format that qemu can
reasonably be expected to read?
If it is, then yes I'd say the image is corrupted. However you'd
probably want to hexdump it to see what's really going on.
Rich.

[PATCH v3 00/11] btrfs support part2: qgroup/quota commands
by Hu Tao
Hi,
This is v3 series to add support to btrfs qgroup related commands, inclduing
quota commands, and two leftover of subvolume commands.
Regards,
Hu
changes:
v3:
- don't intialize fs_buf (patch 1)
- check the return value of sysroot_path (patch 1)
- check fs_buf rather than fs (patch 1)
- fprintf (stderr,...) -> reply_with_error()
v2:
- add tests for new APIs
- combine btrfs_quota_enable and btrfs_quota_disable
- following APIs changed to operate on Mountable_or_Path:
btrfs_subvolume_get_default, btrfs_quota_enable, btrfs_quota_rescan.
Hu Tao (11):
daemon: btrfs: add helper functions mount and umount
New API: btrfs_subvolume_get_default
New API: btrfs_subvolume_show
New API: btrfs_quota_enable
New API: btrfs_quota_rescan
New API: btrfs_qgroup_limit
New API: btrfs_qgroup_create
New API: btrfs_qgroup_destroy
New API: btrfs_qgroup_show
New API: btrfs_qgroup_assign
New API: btrfs_qgroup_remove

Hi,
I noticed the diff wasn't showing the "-" at the start of a deleted file
and the details of the second file when attributes are different.
This change should fix them.
