Subject: [Qemu-devel] ne2000 emulation causes kernel warning/stack-dump in virtual Linux host
Date: Sun, 10 Jun 2007 18:27:56 +0200 [thread overview]
Message-ID: <466C268C.3030808@wanadoo.nl> (raw)
On both qemu (no-kqemu) and qemu-kvm (no-kvm or with kvm) release 0.9.0
the following happens when using ne2000 (default) emulation:
UG: waring at kernel/softirq.c:138/local_bh_enable() (Not tainted)
[<c042b0cf>] local_bh_enable+ /0x92

[..........] sock_map_fd+0x41/0x47
[..........] sys_socketcall+0xac/0x261
[..........] syscall_call+0x7/0xb
The virtual host runs fedora 7, kernel-2.6.21-1.3194.fc7. When using
windows-XP as a virtual host a network hang also occurs, but I have no
details about it.
The mentioned problems (for both Linux and Windows XP) do not occur when
using rtl8139 emulation.
