AWS EC2: cannot get bare metal instance

问题

I have tried several times in the last two weeks to log on to a c5.metal instance. Each time I get "Initializing" in the status checks field, but after 10 minutes it is still "Initializing" and I'm not able to log on. I have had success with c5.metal before, but not any more.

Today I also tried to get an m5.metal instance. This time the instance successfully initialized after 10 minutes but I was not able to log on with Putty. I stopped the instance, then after about 30 minutes I tried again and this time I did not get past "Initializing" in the status check field and I stopped it after 15 minutes.

I get billed for the 10 to 15 minute bare metal wait periods, even when initialization doesn't complete. I have no problems with AWS virtual instances.

Thanks for any ideas on what I can do to get the bare metal instances to work.

To reproduce your situation, I did the following:

Launched an Amazon EC2 instance in Ohio:
- Instance Type: c5.metal
- AMI: Ubuntu Server 18.04 LTS (HVM), SSD Volume Type
- Network: In my Default VPC so that it uses a Public Subnet
- Security Group: Default settings, which grants port 22 access from the Internet
Instance entered running state very quickly, Status Checks showed as Initializing

It took about 8 minutes until the status checks were showing 2/2 checks (it might have been faster, but I was testing other things in the meantime).

I was able to successfully login to the instance:

(Actually, I first tried to login as ec2-user and it took me a while to realize this was an Ubuntu AMI, so I connected as ubuntu).

It is possible that the slow startup is due to the Operating System or hardware checking the 192GB of RAM that is allocated to the instance.

I booted another instance using an Amazon Linux 2 AMI and it required approximately 7 minutes before I could connect.

I also noticed that the c5.metal instances did not provide anything for "Get System Log" or "Get Instance Screenshot". This might be a result of using a bare-metal instance.

I joined John Rotenstein's twitch.tv channel and he showed how he got a c5.metal instance. What I learned is that if a metal instance does not work in the region you had chosen, try launching a new instance in a different data center region. For example, I had a c5.metal instance at us-east-2a. Following John's directions, I launched an instance at us-east-2c and after about 8 minutes the instance was ready for use.
