[opensuse-virtual] Best Practices / Details for Serial Console debug-level logging when using Xen + systemd ?
by ar16 02 Jul '13

02 Jul '13

I boot Opensuse 12.3 + Xen 4.3 using Grub1. Reading http://en.opensuse.org/SDB:Systemd#Getting_debug_from_systemd There's a note to ln -s /usr/lib/systemd/system/serial-getty@.service /etc/systemd/system/getty.target.wants/serial-getty(a)ttyS0.service On my system, I have just: find /usr/lib/systemd/system/ -name *serial-getty* /usr/lib/systemd/system/serial-getty@.service i.e., I do NOT have the symlink for startup in place. I currently have serial console(s) enabled using the config below. It seems to work, but it's evolved to this over time, tweaked as kernel- and xen-versions have changed. I suspect it needs some clean up. My goal is to have grub, early boot, Xen and detailed, debug-level, complete boot logged to both a serial console & video out. What, if anything, SHOULD be changed in the config below for correctness? Specifically, what's recommended for getting the 'right info' form boot process for informative reporting on bugs? cat /boot/grub/menu.lst ... serial --unit=0 --speed=57600 --word=8 --parity=no --stop=1 terminal --timeout=6 serial console ... title Xen root (hd0,0) kernel /xen.gz vga=gfx-1280x1024x16 ... systemd.log_level=debug systemd.log_target=syslog-or-kmsg loglvl=debug guest_loglvl=debug com1=57600,8n1,pci console=vga,com1 console_timestamps ... apic_verbosity=verbose iommu=verbose ... module /vmlinuz-xen log_buf_len=4M console=tty0 console=xvc0,57600n8 xencons=tty earlyprintk=xen vga=0x31a ... showopts noquiet module /initrd-xen ... -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-virtual+owner(a)opensuse.org

[opensuse-virtual] howto change virtual machine creation defaults
by Rob Verduijn 18 Jun '13

Hello, I want to change the defaults when a new vm is created. ie now the default hd is a raw image that is fully allocated when you create a vm. I would like to change it to qcow2 sparse image. Does anybody know how to do this or where to find documentation for this ?

[opensuse-virtual] future of XEN (within SuSE)

Hi all, It could be just my perception, but i've got the feeling that more and more attention is given to KVM, and i wonder if this is intentionally? For instance, on http://doc.opensuse.org/ it is about "Virtualization with KVM" in htmp, pdf and epub, while not a single word about XEN or LXC... Intentionally? I got quite some paravirtualized servers, this is seriously worrying me. And as a long term XEN user, should i start looking for an alternative distro in case SuSE is going to drop XEN?

Hello, Thank you for your response. It is indeed trivial to change the default extension of the filename. But then again, so is changing the imagetype with qemu from raw fully allocated to qcow2 sparse and then editing the virtual machine properties with virsh edit. (or at least it is for me) It takes a little more effort to create a template xml or a huge one liner to create a new vm. Most things are not to difficult, but I just want the damn thing to do this for me by default. It wouldn't be the first time that after I finished creating a new vm I would notice it has the wrong image type, or the wrong video card (cirrus in stead of qxl) , incorrect display (vnc in stead of spice) etc etc. ( hence the trivial editing of kvm vm's afterwards for me) I'm getting tired of that, and I don't like modifying my xml-template or oneliner scripts everytime i create a vm. I would really appreciate it if I could explain to libvirt, to use sparse qcow2 images, qxl video card, spicy display, usb redirection etc etc by default Rob 2013/6/11 Tony Su <tonysu(a)su-networking.com>: > You'll have to describe how you're creating your machine. > > If you use libvirt (eg vm-install from App Launch menu, Yast or vm > manager), AFAIK simply changing the filename extension changes the > disk format and this is next to trivial simply by clicking on the > "details" disk property link. > > You might also find it easy to simply create your machine from the > CLI, after you do it the first time you have your template and it's > simple enough to do afterwards. > > Tony > > On Mon, Jun 10, 2013 at 11:40 PM, Rob Verduijn <rob.verduijn(a)gmail.com> wrote: >> Hello, >> >> I want to change the defaults when a new vm is created. >> ie now the default hd is a raw image that is fully allocated when you >> create a vm. >> I would like to change it to qcow2 sparse image. >> Does anybody know how to do this or where to find documentation for this ? >> >> Regards >> Rob >> -- >> To unsubscribe, e-mail: opensuse-virtual+unsubscribe(a)opensuse.org >> To contact the owner, e-mail: opensuse-virtual+owner(a)opensuse.org >> -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-virtual+owner(a)opensuse.org
