Solaris 10 64bit guest hangs with high Xorg cpu usage on Solaris 10 64bit host

Reported by: tom1978 Owned by:
Priority: major Component: other
Version: VirtualBox 3.0.8 Keywords: Xorg
Cc: Guest type: Solaris
Host type: Solaris

Description

Host: Solaris10 s10x_u8wos_08, VirtualBox 3.0.8 installed on Sunfire x4150. (AMD-V enabled, nested paging enabled)

Guest: Solaris10 s10x_u8wos_05, guest additions installed. (AMD-V enabled, nested paging enabled for all guests)

The Xorg cpu usage climbs to above 90% and the Xorg hangs. This occurs when a guest is sitting idle and also during more intensive applet testing. This only occurs on the 64bit guest, 32 bit is fine. Is this a known issue?

We solved a similar bug relating to the guest shadow page tables not being updated with the proper access bits a couple of months back.

Could you try with nested paging off and see if it helps?

Replying to ramshankar:

I have seen the same behaviour regardless of whether nested paging is enabled. I run 6 guests on 3 x4150's. 6 RHEL 5.4 on one server, 6 Windows XPpro SP3 on another and 6 Solaris 10 s10x_u8wos_05 on the third. At least one or two of the Solaris guests are in a hung state each morning even when nothing has been run on them.

Without the VBox.log of such a session there's not much we can say.
