[Libvir] Use virsh to monitor qemud
by Fabian Deutsch 03 Jun '07

03 Jun '07

Hey, I jsut installed Fedora 7 and tried to install some guests and it worked like a charm. I use qemu for full virtulization. A couple of minutes later i stumbled across libvirts virtsh. But now I wonder how I cna use virtsh to connect to qemud - all I get is something like: "Can't connect to hyperisor." - fabiand

[Libvir] SOLVED Re: cannot use vncviewer and VMM graphics console to access HVM guest on RHES 5
by Glen Deem 03 Jun '07

03 Jun '07

Thanks to Igor Chubin (spasibo) and Richard Jones, the qemu vnc server was listening but I did not connect to its proper port (why libvirt doesn't use <IP>:<domU id> kind of vnc connection and restricts the server to local host only by default?).

Hi Dan, I'm with you about the VNC authentication. But I still don't understand the logic behind assigning HVM displays. Instead of clear "domU ID is the display number" (vncunused 0), the Virtual Machine Manager assigns vncunused to 1 and then calculates the 5900+ port, I suppose depending on what port is not occupied (BTW where exactly is this code in the source, please?). Why is that? And how am I suppose to find out what that port number is if I'd want to connect to a VMM-created vm manually with my vnc client? Thanks, Glen Daniel P.

[Libvir] cannot use vncviewer and VMM graphics console to access HVM guest on RHES 5
by Glen Deem 01 Jun '07

Hi all, I've created an HVM guest under RHES 5 (Xen 3.0.3) using "xm create" but I cannot access it with vncviewer. The Virtual Machine Manager also informs about graphics console unavailability. What am I doing wrong, please? I do > vncviewer 123.456.789.123:4, where 4 is the guest id. This is the xm config file is: name = "hvmGuest" builder = "hvm" memory = "500" disk = [ 'file:/var/lib/red-hat.img,hda,w', ] vif = [ 'type=ioemu, mac=00:16:3e:34:3b:ba, bridge=xenbr0', ] device_model = "/usr/lib/xen/bin/qemu-dm" kernel = "/usr/lib/xen/boot/hvmloader" vnc=1 vncunused=1 apic=1 acpi=1 pae=1 vcpus=1 serial = "pty" on_reboot = 'restart' on_crash = 'restart' Thanks a lot in advance.

My fault. I'll fix it.

I'll pay attention on that. Not clear what the postrm was for. Is there configuration kept in > /usr/share/virt-manager? My fault. I'll checked it. Thanks

Hello, I compiled the libvirt from last cvs source without to export CFLAGS -fstack-protector option without problem. After it, I compiled the virt-manger and it isn't working.

[Libvir] Finally - fix the build on Debian
by Richard W.M. Jones 29 May '07

29 May '07

The attached patch fixes three separate build problems on Debian: (1) The libtool autoconf macro is wrong in that it requires a C++ compiler and /lib/cpp, neither of which seems to be really needed. (2) If you pass -fstack-protector while compiling, then you also need to pass it while linking, so that gcc knows to link -lssp. (3) Long-standing problem that xencapstest.c won't compile --without-xen. Well, OK so I didn't actually fix (1), but I did add a note to the TODO file pointing out the problem. So you'll still need to install the Debian "g++" package before you can compile libvirt.
