We have ASR configured to replicate a bunch of VMs from a Hyper-V host to Azure. Most Guest VMs are replicating successfully however one is constantly failing. This is the only Linux VM on the host and it's been configured with 40GBs of memory - not sure if either of those elements have anything to do it with (obvs we're selecting Linux as the OS in ASR).
The errors we're getting in the host event log for ASR are:
"Export System Definition for virtual machine 'XXXX' failed"
"The configuration file for virtual machine 'XXXX' could not be sent to the Azure Site Recovery. You may not be able to failover back your virtual machine on your host if it gets deleted from the host"
"Replication operation for virtual machine 'XXX' failed"
I did find the following article and tried this but no difference: https://blog.davesdomain.co.uk/hyperv-to-azure-config-file-24mb-limit/
Any suggestions appriciated
Thanks
