VMware Workstation 10 on CentOS 6 Host with Windows 7 Guest Running iTunes

1 Comment

After installing iTunes on a Windows 7 guest, I would then plug my iPhone into a USB port on my CentOS 6 host. Inside of VMware Workstation 10, I selected the appropriate VM, then from the menu bar I selected VM > Removable Devices > Apple iPhone > Connect (Disconnect from host). This causes VMware to attach this USB device to the Windows guest instead of the CentOS host.
After doing this, I get the following message from VMware: “The Device “Apple iPhone” was not able to connect to its ideal host controller. An attempt will be made to connect this device to the best available host controller. This might result in undefined behavior for this device.”

Go to Start > Devices and Printers. You should see two new devices under the Unspecified section called “Apple Mobile Device USB Driver” and “Apple iPhone”.

Also, if you open up Explorer and go to Computer, you should see your iPhone listed as a Portable Device.

After browsing files on the iPhone within Explorer (using the iPhone as an internal storage device), I get a Windows blue screen including the message “BUGCODE_USB_DRIVER”. The guest machine crashes while the host remains stable.

Alternatively, if I opened iTunes while the iPhone is attached to the Windows guest, iTunes would display the error “iTunes could not connect to the iPhone because an invalid response was received from the device.”

Ultimately, I resolved the majority of my issues by powering off the Windows guest VM, going to VM > Settings > USB Controller >
Change USB Compatibility from USB 1.1 to USB 2.0. Save and restart the VM.
Every once in a while iTunes does not recognize the iPhone. Usually this can be resolved, by removing and re-adding the iPhone or closing and re-opening iTunes. Sometimes by adding the iPhone prior to starting iTunes.
In order for Sync over Wi-Fi to work, the guest Windows VM running iTunes should to have an IP on the same physical network as your iPhone. Power off the guest VM, go to VM > Settings > Network Adapter >
Select “Bridged” instead of “NAT”.

My System Configuration

  • VMware Workstation 10.1
  • Host: CentOS 6.5 x86 64-bit
  • Guest: Windows 7 Professional SP1
  • iTunes 11.1.3.8

CentOS Host OS Crashes When Installing VMware Tools on a Guest OS Within VMware Workstation 10

6 Comments

Installing VMware Tools on a Windows 7 Guest OS in VMware Workstation 10.1 running on a CentOS 6 host always resulted in the host OS crashing.
This appears to be due to a combination of VMware Workstation 10.1 running on CentOS 6 .5 with kernel 2.6.32-431.1.2.0.1.el6.x86_64 #1 SMP x86_64 GNU/Linux. I see these two interesting items on the screen output followed by a call trace.

BUG: scheduling while atomic: vmware/6035/0x000002000
Pid: 6035, comm: vmware Tainted: G D --------- 2.6.32-431.1.2.0.1.el6.x86_64 #1

To resolve this issue:

# service vmware-workstation-server stop
# service vmware stop
# mv -v /usr/lib/vmware/modules/binary /usr/lib/vmware/modules/binary~orig
# rm /lib/modules/$(uname -r)/misc/v*.ko
# depmod -a
# yum install make gcc keneral-headers-$(uname -r) kernel-devel
# /usr/bin/vmware-modconfig --console --install-all
# service vmware start
# service vmware-workstation-server start

I could now attempt to install VMware Tools on a Windows 7 Guest OS without the host crashing. However, I now ran into another complication. The VMware Tools install would hang around the point of installing the ThinPrint module. Basically, the VMware Tools install hangs due to cruft left over from previous install attempts. Follow VMware KB Article 1001354 to remove cruft left over from previous VMware Tools installs. Then try reinstalling again.
You do not need to repeat this procedure since the offending modules are being removed in the steps above. During subsequent kernel upgrades, modules will be recompiled automatically.
VMware claims that “this issue should be fixed with the next update (10.0.2), and we will publish a kb article.”
UPDATE: The VMware community appears to agree that this issue is resolved in the Workstation 10.0.2 release.

My System Configuration

  • VMware Workstation 10.1
  • Host: CentOS 6.5 x86 64-bit
  • Guest: Windows 7 Professional SP1

Install a Desktop Environment on CentOS 6 Minimal Install

8 Comments

After performing a base install of CentOS 6 using the minimal install CD, do the following to install a basic GNOME desktop environment:

# yum groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts"

Run the following on a particular package group in order to see detailed information including a description and which packages it will install.

# yum groupinfo groupname

There are additional package groups if you want something more than a basic desktop environment. For example,

# yum -y groupinstall "General Purpose Desktop"

To see a list of all the installed and available package groups:

# yum grouplist

Once installed, you can start GNOME by running:

$ startx

or

$ /sbin/telinit 5

To have CentOS boot into runlevel 5 “X11” instead of runlevel 3 “Full multiuser mode”, modify the /etc/inittab file to change start up level from

id:3:initdefault:

to

id:5:initdefault:
