I second all of @pilow points. We have been running a lot of Dell R630's with Intel CPU, Intel NIC, PERC H730i raid-cards and it has been flawless. Now we're using Dell R660's, but with newer spec's.
Tried Broadcom NIC's once, it worked, but had some weird performance issues from time to time.
Go with shared storage, NFS if possible (thin provisioning) and avoid XOSAN/XOSTOR, I don't think its battle-tested quite yet.

RE: CloudConfigDrive removal
Ok, my syntax is oudated.
resize_rootfs: true growpart: mode: auto devices: ['/dev/xvda3'] ignore_growroot_disabled: false runcmd: - pvresize /dev/xvda3 - lvextend -r -l +100%FREE /dev/ubuntu-vg/ubuntu-lv || truethis one works.
final_message.doesn't support any macro like%(uptime) %(UPTIME) -
RE: Every virtual machine I restart doesn't boot.
It is difficult to know the source of the problem without more details from your logs. Can you run the following commands on your XCP-ng host and then attach the generated files here?
grep -A 15 -B 15 -i error /var/log/xensource.log/xensource > xensource.txt grep -A 15 -B 15 -i exception /var/log/SMlog > smlog.txt dmesg -T|grep -Eiv 'guest|capacity|promiscuous' > dmesg.txt -
Unable to copy template
Can't copy VM template to some pools, but it still works with other.
