Results are in...

Four VMs migrated. Three using warm migration and all worked. 4th used straight migration and BSOD but worked after a reboot.

@olivierlambert

Thanks Oliver. We have used GFS with Veeam previously and will be a great addition.

@olivierlambert

We have successfully installed using:

rpm -Uvh https://repo.zabbix.com/zabbix/7.0/rhel/7/x86_64/zabbix-release-latest.el7.noarch.rpm
yum install zabbix-agent2 zabbix-agent2-plugin-* --enablerepo=base,updates

@BenjiReis

Worked perfectly. Thanks guys.

@olivierlambert

Thanks Oliver, lots to learn.

p.s. Congrats on the 8.3 launch.

Our Hyper-V servers have no GUI and the process I use is:

1. RDP to the Hyper-V host
2. Open PowerShell
3. Get a list of the VMs on the host

    Get-VM

4. Stop the VM

    STOP-VM -Name <name of VM>

5. Identify the VM's disk(s) for conversion

    Get-VMHardDiskDrive -VMName <name of VM>

6. Convert the VHDX to VHD (destination file extension sets the type so use ".vhd")

    Convert-VHD -Path <source path> -DestinationPath <destination path> -VHDType Dynamic

To transfer the newly created .vhd files to xcp-ng we use Putty via the cli

@thomas-dkmt

Either way.

1. If you can have the server offline then shutdown and create the VHD from the VHDX. The process creates another disk file so the original remains unchanged and if it all goes wrong you can simply restart the VM in Hyper-V and try again another day. You will need enough disk space for the original VM & the new VHD file.

2. If the server cannot be offline then export the VM and then convert the VHDX to VHD. The issue being the original will VM still be updated whilst the migration to xcp-ng takes place. You will need enough disk space for the original VM, the exported VM and the new VHD file.

@olivierlambert

We have a simplified process now.

• Shutdown VM in Hyper-V
• Convert VHDX to VHD using PowerShell
• Move VHD to xcp-ng using SSH
• Generate new name using uuidgen
• Rename VHD
• Create VM in XO and attach VHD

After much trial and error this works every time.

Is there any way to paste from the console?

We have long passwords for Windows and these need to be typed manually to obtain console access which is a real pain.

Tried many times without success.

1. Exported vhdx from Hyper-V
2. Converted to VHD (Tried Powershell & StarWind)
3. Changed name to UUID name
4. Scan of disk fails

What am I missing?

I have delta backups that are excessive in size and I wish to compare two using WinMerge
https://winmerge.org/

How can I restore only the disks from two delta backups so they can be attached to an existing VM?

Q1) Is it possible to change the management interface via XOA? I can do it via XS console & I am sure via CLI too.

Q2) What is the significant of the management interface? As I can assign it to one of many interfaces the question is which is the best one to select.

Thanks

@olivierlambert

I need a new ID for Active Directory, otherwise AD things both VMs are the same computer.

In Hyper-V when I export and import a VM I can assign a new ID

In XO/XOA how can I copy a VM and assigned a new ID?

@DustinB

Emergency Reset Worked. ty

I need to move my hosts to a new network.

I have reconfigured the network interface and now the host shows "No interface configured"

I am still able to ping the host.

As the network has changed, the slave is no longer able to communicate with the master.

I am unable to access the interface to put it back to the way it was before.

What is the best way to proceed? I am happy for this host to be totally removed from the pool.

@olivierlambert

Is this listed on GitHub so I can track any discussion/progress?

I am keen to see this implemented as currently we receive backup reports of failed jobs and have no idea which host is came from.

@olivierlambert

Whilst this request awaits implementation. If I check all hosts individually however I identify the host based upon the jobID or runID from the notification?

Happens over and over?
