Hi,
I am currently testing Xen on my laptop and was wondering if there was
any way to enable ACPI sleep so that I can resume sessions when I''m
on
the go. Is this possible? If so, could you please highlight how to
achieve this? Thank you.

Hello all, Does anybody know how can I share character device over the network? I know how to share block devices: GNBD, AoE and so on. But have no clues about sharing character devices, like /dev/ttyS0 for example. I''m aware of http://www.faqs.org/docs/Linux-mini/Linux-Modem-Sharing.html but I want to find other possible solutions. This task is related to Xen U-domains live migration. Thank you for any ideas. -- WBR, i.m.chubin _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

It seems it''s not so easy to make it working for the kernel and xen hackers. for the guests, you could use xen''s save and restore mechanisms.

Thanks Henning. I had read over at http://lists.xensource.com/archives/html/xen-users/2007-02/msg00147.html that the Xen team has basic support for Xen S3 (x86-32/PAE) in house working but that the patch still needs a little work and was wondering if the situation has been updated yet or not. Here''s the exact wording: "We have basic support to Xen S3 (x86-32/PAE) in house, but patch still needs rebase and a bit cleanup. We''ll send out for review soon once ready.

I thought you were simply trying to reach a serial port on the remote machine. If so, why can''t you SSH to the remote machine and use Kermit or a similar tool to access it from the remote machine? Or do you really need that serial port accessible directly over your local network, for some reason? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

In ideal, I''d like to have /dev/ttyXXX character device file, which maps to character device of another host, accessible via network. Like GNBD for character, not for block devices. May be I could map pseudoterminal device like /dev/pts/* to external character device? -- WBR, i.m.chubin _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

RE: [Xen-users] Xen and ACPI Sleep
Hello, As far I have heard from Mats, save and restore do not work yet for Windows HVM domains...

I''m currently testing Save/Restore more or less daily, reporting whatever problems I see back to XenSource, as does some people at Intel. -- Mats> > Archie > > -----Original Message----- > From: xen-users-bounces@lists.xensource.com > [mailto:xen-users-bounces@lists.xensource.com] On Behalf Of > Henning Sprang > Sent: Tuesday, April 10, 2007 5:47 PM > To: Mathew Brown > Cc: xen-users@lists.xensource.com > Subject: Re: [Xen-users] Xen and ACPI Sleep > > On 4/10/07, Mathew Brown <mathewbrown@fastmail.fm> wrote: > > Hi, > > I am currently testing Xen on my laptop and was wondering > if there was > > any way to enable ACPI sleep so that I can resume > sessions when I''m on > > the go.
