backup import issue

Submitted by hescominsoon on Tue, 09/03/2019 - 08:34 Pro Licensee

I am importing a backup from another server of mine. The virt version is the same but it is coming from ubuntu 16.04 lts to ubuntu 18.04 lts. The issue i am seeing is it is trying to import onto an existing ipv6 address instead of the next available. ipv4 is a shared address ans is not throwing an error.
Adding IPv6 address 2604:4100:2:7:0:0:0:3 .. .. IPv6 address failed! : Failed to add IPv6 address : SIOCSIFADDR: File exists Here is another error inside of virt: No virtual servers containing 2604:4100:2:7:0:0:0:3 were found.

however that ip is assigned to: 2604:4100:0002:0007:0000:0000:0000:3 (Dedicated IP) aminerdetail.com

why is virt trying to stomp on an existing ipv6 address?

I went and manually removed all of the imported domains and i had to manually clear multiple .3 entries in the networking file. I then added .3 back to AMD and the others got allocated properly. So it borked itself the first time but worked properly the second.

I tried importing one of the domains(it is a single 4.5 gig archive made by virt) and it incremented the ipv6 correctly. Only when i try to import all of them at once..the first one increments..then the rest attempt to stack on top of the same ip..even though i have the restore options set to assign an individual ipv6 address

after i cleared things out now it is stuck on .5 Adding IPv6 address 2604:4100:2:7:0:0:0:5 .. .. IPv6 address failed! : Failed to add IPv6 address : SIOCSIFADDR: File exists

i have attached a couple of screenshots of what it is doing to the netplan and the restore settings i am using(and have used many times in the past). this is a freh install so any anomalies are most likely bugs.

here's some more errors: No virtual servers containing 2604:4100:2:7:0:0:0:5 were found.

except for this: 2604:4100:2:7:0:0:0:5 (Dedicated IP) 21 virtual servers

the domains did not exist on the server before the import.

Ah, so the real issue is that IP allocation isn't taking into account allocations made during the same restore?

i wound up nuking the box because of other non-virt issues(web1). will report back if it reoccurs.
