Hello Fengping,
From one VM we need to see the output of “ip a”, “ip route”, “ip -6 route”. It can be also good to see the status of the network service (network, NetworkManager whichever is active).
Hello Jeet,
Your VM encountered the same problem as you pointed out, VM was forcefully stopped. I started the VM, checked some indicators on the hypervisor. I expect that your VM will be running fine. We have some possible fixes, however we are not able to deploy at the moment.
Also, on the FABRIC-UCSD, all VMs (yours as well as other users’) are running on ucsd-w3 and ucsd-w4. You can consider using the other ones (ucsd-w1, ucsd-w2, ucsd-w5) for VMs that require large memory.
Please let us know if you encounter difficulties.
Best regards,
Mert
This problem was caused by a transient problem on the hypervisor, and VM was forcefully stopped. VM is restarted and accessible. We will work on the root cause of the problem internally, but you should be able to continue your work on the VM.
We are in the process of adding Debian 11 (Bullseye) image to all FABRIC sites. We will notify when this image can be used in your notebooks.
Following subnets are used for control interfaces of the VMs on all sites.
[1] 10.20.4.0/23
[2] 10.30.6.0/23Update:
For the EDC site (special RACK for Measurement VMs) following subnets are used:
[1] 10.40.4.0/23
[2] 10.40.6.0/231 user thanked author for this post.
This outage is resolved. VMs on FABRIC-NCSA rack are reachable from public internet. Please let us know if you encounter any problems.
We are working with the hosting campus for a known network issue that may require part replacement. No ETA is available, updates will be posted when the problem is resolved.
If you create an example slice to reveal the problem, we can work on it to understand better, suggest solutions, consider changes on public ACLs. Please let us know with the name of the slice and FABRIC site, if this sounds good for you.
Does it mean that TACC site is not support IPv6?
Yes, TACC site does not support IPv6, it supports IPv4 addresses.
Sites MAX, TACC (and upcoming MASS) support only IPv4 addresses.
Sites STAR, MICH, UTAH, NCSA, WASH, DALL, SALT support only IPv6 addresses.
