First - VMware performance is not really an issue of iSCSI (on FreeNAS) or NFS 3 or CIFS (windows) protocol, its an issue of XFS filesystem writes and the 'sync' status. FreeNAS has a property called "sync" and it can be set on or off. "zfs sync=always" is set by default and causes every write to be flushed. This dramatically slows performance but ...

On the host, you have to create a second virtual network that contains your iSCSI NIC's. Then you can add a NIC to the guest attached to that network. That gives you access to the iSCSI network inside the guest. However, Hyper-V does not support booting guests directly from iSCSI. You have to chainload in to iPXE or something similar.

If I doesn't work, try detaching and re attaching the virtual drive. If still doesn't work, you should see if you have snapshots of the VMs. What did work ...

The following syntax works for me for discovering new iSCSI devices. Note the extra -D parameter: # iscsiadm -m discovery -t sendtargets -p 255.255.255.255 -D 255.255.255.255:3260,1035 iqn.1992-08.com.netapp:foobar 255.255.255.255:3260,1036 iqn.1992-08.com.netapp:foobar 255.255.255.255:3260,1037 iqn.1992-08.com.netapp:foobar 255.255.255.255:3260,1034 ...
