Hi all,

We currently have this setup: 4 nodes running identical hardware and software, 1 san, 2 switches

1) We have run into another strange issue. We have a KVM VM up and we can live migrate from any of nodes 1-3 but on node 4 it says the below. Now if we go into options and turn off hardware virtualization, it works - we're wondering why this is the case for just 1 node?

online migrate failure - command '/usr/bin/ssh -c
blowfish -o 'BatchMode=yes' root@10.10.1.156 qm start 101 --stateuri tcp
--skiplock' failed: exit code 255
ERROR: migration problems

2) Also we keep getting duplicate issues whenever we migrate a KVM VM

Found duplicate PV - it works fine but scrolls all of this ... is this an issue?

3) We also got an error that said "no accelerator found" on node 4 - CPU virtualization is enabled in bios though

After enabling that in the bios, you powered off that node? If not, power off, and then try again.
 
I have no information about your storage setup, so it is impossible to answer the question. I guess your iscsi storage is accessible via different networks?
 
iSCSI SAN is connected to 2 switches. 8 ports on each. Nodes connected to both switches 1 port on each - all in same VLAN. the 2 switches are trunked via a 4 x 1GBPS port trunk group.

I technically have 2 private IPs and each SAN NIC has 1 IP (this may change if we start bonding the NICs on the SAN)

Thank you
