[Libvir] no vfb for paravirt guest on RHEL 5 and strange args
by Glen Deem 12 Jun '07

12 Jun '07

Hi all, I'm creating a fairy simple paravirt machine under RHEL 5 (Xen 3.0.3, pygrub 0.6). A machine gets created but I see two problems: 1. no graphics console gets enabled (so RedHat VMM does not open it) so I cannot connect to it with vncviewer (am I naive to use vfb fpr a paravirt domU? - libvirt uses it, right?); 2. when I check what config has been used to create the domain (in /var/log/xen/xend.log) I see arguments ("args" or "extra") picked up from a virtual machine created a while age, my present "extra" parameter is ignored. I did regenerate xenstored/tdb and rebooted, still those args appear, drives my nuts :-). I'm actually after the graphics console, but I think both problems are related. Could anybody advise why I get no proper vfb setup (I'd expect a vnc-port vaue appearing in the xen store when it setup properly) and why I get those old args? Thanks in advance, Deem P.S. xm config ============ name = "para-2" memory = "256" disk = [ 'file:/var/lib/para-2.img,hda,w' ] vif = [ 'bridge=xenbr0' ] vfb = ['type=vnc, vncunused=1'] bootloader='/usr/bin/pygrub' vcpus=1 on_reboot = 'restart' on_crash = 'restart' extra = 'ignored' from /var/log/xen/xend.log: ================== [2007-06-12 17:13:56 xend.XendDomainInfo 5445] DEBUG (XendDomainInfo:940) XendDomainInfo.handleShutdownWatch [2007-06-12 17:41:57 xend.XendDomainInfo 5445] DEBUG (XendDomainInfo:190) XendDomainInfo.create(['vm', ['name', 'para-2'], ['memory', '256'], ['on_reboot', 'restart'], ['on_crash', 'restart'], ['vcpus', 1], ['bootloader', '/usr/bin/pygrub'], ['image', ['linux', ['ramdisk', '/var/lib/xen/initrd.NMeE1x'], ['kernel', '/var/lib/xen/vmlinuz.7QoaTW'], ['args', 'nosplash quiet rw acpi=on XXHOST=localhost.localdomain XXLDAP=127.0.0.1 resume2=swap:/dev/mapper/XxxxxxVG-swap vga=791 root=/dev/XxxxxxxVG/root']]], ['device', ['vbd', ['uname', 'file:/var/lib/para-2.img'], ['dev', 'hda'], ['mode', 'w']]], ['device', ['vif', ['bridge', 'xenbr0']]], ['device', ['vkbd']], ['device', ['vfb', ['vncunused', '1'], ['type', 'vnc'], ['display', ':0.0'], ['xauthority', '/root/.xauthfLRNzX']]]])

[Libvir] New vs old-style hypercalls
by Richard W.M. Jones 12 Jun '07

12 Jun '07

In xen_internal.c we've got code which claims to sniff out whether we are using new-style hypercall ioctls or old-style hypercall ioctls. hc.op = __HYPERVISOR_xen_version; hc.arg[0] = (unsigned long) XENVER_version; hc.arg[1] = 0; cmd = IOCTL_PRIVCMD_HYPERCALL; ret = ioctl(fd, cmd, (unsigned long) &hc); if ((ret != -1) && (ret != 0)) { #ifdef DEBUG fprintf(stderr, "Using new hypervisor call: %X\n", ret); #endif hv_version = ret; xen_ioctl_hypercall_cmd = cmd; goto detect_v2; } /* * check if the old hypercall are actually working */ v0_hc.op = __HYPERVISOR_xen_version; v0_hc.arg[0] = (unsigned long) XENVER_version; v0_hc.arg[1] = 0; cmd = _IOC(_IOC_NONE, 'P', 0, sizeof(v0_hypercall_t)); ret = ioctl(fd, cmd, (unsigned long) &v0_hc); But on 64 bit platforms (not 32 bit) cmd will be identical, so we'll just be trying the same ioctl twice. From <xen/linux/privcmd.h>: typedef struct privcmd_hypercall { __u64 op; __u64 arg[5]; } privcmd_hypercall_t; #define IOCTL_PRIVCMD_HYPERCALL \ _IOC(_IOC_NONE, 'P', 0, sizeof(privcmd_hypercall_t)) From src/xen_internal.c: typedef struct v0_hypercall_struct { unsigned long op; unsigned long arg[5]; } v0_hypercall_t; cmd = _IOC(_IOC_NONE, 'P', 0, sizeof(v0_hypercall_t)); On 64 bit platforms, both structures will be the same size.

I'm merging the remote patch into libvirt CVS. Things may break, although I'm hoping to keep any brokenness to a minimum.

[Libvir] Suggested list of files to rename

I've accumulated a collection of files in libvirt which I think should be renamed. This file is in CVS, called 'RENAMES', and attached below. What do you think?

[Libvir] PATCH: Fix bridge device handling with xm config files
by Daniel P. Berrange 07 Jun '07

07 Jun '07

The code for parsing xm config files & generating XML forgot to add in the <source bridge='xenbr0'> elements if an explicit bridge is requested. The reverse direction was already implemeneted. This patch fixes the missing handling of bridge devices & adds a test case Dan -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=|

[Libvir] [PATCH] add bootloader_args to libvirt xml to support bootloaders (like pypxeboot for example) that require arguments
by Hugh Brock 07 Jun '07

07 Jun '07

This patch extends libvirt's XML to include a paramater Xen already supports in sexpr, "bootloader_args." The bootloader_args parameter lets you pass arguments -- "mac=aa:12:34:56:78:90" for example -- to a bootloader program that xend invokes when it starts a guest. One such program, pypxeboot, uses the mac= argument to communicate with a dhcp server and retrieve the pxeboot kernel and initrd for a paravirt guest. The patch includes new tests for the bootloader_args XML and sexpr, which pass. Note that for the head of current libvirt, the virsh tests do not pass and virsh will not connect to the xen hypervisor. I don't know if this is my own build environment or some other issue. However the failure is the same with or without this patch, so I am submitting it anyway. Please let me know what you think... --Hugh -- Red Hat Virtualization Group http://redhat.com/virtualization Hugh Brock | virt-manager http://virt-manager.org hbrock(a)redhat.com | virtualization library http://libvirt.org
