Problems with the new ioemu

Problems with the new ioemu

[Dugger, Donald D]

We've encountered a few problems with the new ioemu tree:

ssue1: with vncviewer enabled by 'vnc=1 & vncconsole=1', 
qemu-dm exit(1) for invalid option '-vncviewer'
qemu.log:

/usr/lib64/xen/bin/qemu-dm: invalid option -- '-vncviewer'

Even with vncviewer disabled by 'sdl=1' or 'vnc=1 & 
vncconsole=0', still failed to create hvm guest:

Issue2: if no vif option set and vncviewer disabled, qemu 
exits abnormally with following log:

It is recommended that you use gcc 3.x to build QEMU
To use this compiler anyway, configure with --disable-gcc-check

Hello,

Which version are you using?  Some of the errors you are reporting
should have been fixed by now:

I'll let Haicheng comment on the I/O request, that's really his bug not mine.

in re: GCC v. 4 - I just did a `hg pull' (changeset: 18074:23208dc42cfe), `make distclean && make' and got the same error, it still requires GCC v. 3.

Re: Problems with the new ioemu

[Jean Guyader]

You should do a git pull inside ioemu-remote.

RE: Problems with the new ioemu

[Dugger, Donald D]

So the top level makefile does a `git pull' if the `ioemu-remote' directory doesn't exist but it doesn't do the pull if it does?  That seems a little inconsistent.

Also, I thought the purpose of `make distclean' was to remove everything that wasn't part of the tree, especially given that it will remove the Linux kernel subtree shouldn't it also remove the `ioemu-remote' directory?

Ignoring the fact that `git pull' in the `ioemu-remote' directory did nothing, just said:

Already up-to-date.
