#16945 fixed SPDK needs a delay between creating an I/O queue pair and sending I/O commands in Virtualbox => fixed in SVN/next maintenance crane
Description

We are testing SPDK in Fedora25 in Virtualbox, and find its hello_world demo would hang after repeating several times. SPDK team found the workaround way in SPDK, and commit here: https://github.com/spdk/spdk/commit/13f8cf1536ca5222878d2c03802fb367e1340ef9

It gives a 100us delay to Virtualbox after allocating an I/O queue pair. However, on another platform, we found the delay should be enlarged to 1000us to make SPDK hello_world test pass.

Here is the hello_world's procedure:

  1. admin cmd1: create one IO CQ
  2. wait until cmd1 completion
  3. admin cmd2: create one IO SQ
  4. wait until cmd2 completion
  5. delay 100us (or 1000us in my platform, but hope it could be eliminated)
  6. IO cmd3: write data
  7. wait until cmd3 completion <===== HANG here
  8. ...

Does Virtualbox NVMe device sends CQ too early?

#16944 invalid Can not connect to Oracle 12c in the guest - Virtualbox 5.x - Host Mac OS Sierra 10.12.5 - Guest Windows 7 Ultimate fserrano
Description

I am using a host Mac OS X Sierra 10.12.5 and I have a guest with Windows 7 Ultimate installed and I can not connect from the host to the Oracle 12c R1 installed on the guest. I also have MySQL and DB2 installed in the guest and I can connect to both of then with no problem. Windows Firewall is off. The ping works with host pinging the guest. If I access Oracle from inside the guest it works ok also. I have already tryied to use NAT and Host-only Network adapters and none of them work. I have had this machine working since I used host Mac OS X Mountain Lion 10.8 with Vitualbox 4.3, it worked perfectly. When I updated to Mac OS X Sierra 10.12.5 I had to update the Virtualbox to 5 and than I started to have this problem that is still the same on Virtualbox 5.1.24. I have already tryied to install Windows 10 in Virtualbox 5.1.22 and had the same problem.

The error that I receive when I try to connect is: Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection.
