by Richard W.M. Jones 30 Jul '11

30 Jul '11

The guest filesystem browser lets you browse guest filesystems, the Windows Registry, and other bits from guests. You can see some screenshots here: https://rwmj.wordpress.com/2011/07/29/some-screenshots-from-the-new-guest-f… The 0.2.1 release includes lots of new functionality, including: - looking at inspection data, applications, drive mappings and more - looking at detailed file information, extended attrs - ability to view arbitrary disk images The home page is here: http://people.redhat.com/~rjones/guestfs-browser/ I have pushed relatively recent builds into Fedora 15, Fedora 16 and Rawhide. For F15 and F16 you'll need to get the latest from updates-testing: https://admin.fedoraproject.org/updates/search/guestfs-browser Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones New in Fedora 11: Fedora Windows cross-compiler. Compile Windows programs, test, and build Windows installers. Over 70 libraries supprt'd http://fedoraproject.org/wiki/MinGW http://www.annexia.org/fedora_mingw

[libvirt] Changing device owner
by Shahar Havivi 30 Jul '11

30 Jul '11

Alex, Regarding vdsm changing a device owner, Last time I asked in #virt for using usb device in vdsm hook in /dev/bus/usb/<addr> I was told that vdsm should change the owner to qemu:kvm. So for the sr-iov device /sys/bus/pci/devices/<addr>/resource*, rom, and reset libvirt should change the owner and not vdsm? Shahar Havivi.

[libvirt] [PATCH] network: don't forward DNS requests from isolated networks
by Laine Stump 29 Jul '11

29 Jul '11

This is in response to: https://bugzilla.redhat.com/show_bug.cgi?id=723862 which points out that a guest on an "isolated" network could potentially exploit the DNS forwarding provided by dnsmasq to create a communication channel to the outside. This patch eliminates that possibility by adding the "--no-resolv" argument to the dnsmasq commandline, which tells dnsmasq to not forward on any requests that it can't resolv itself (by looking at its own static hosts files and runtime lsit of dhcp clients), but to instead return a failure for those requests. This shouldn't cause any undesirable change from current behavior, even in the case where a guest is currently configured with multiple interfaces, one of them being connected to an isolated network, and another to a network that does have connectivity to the outside. If the isolated network's DNS server is queried for a name it doesn't know, it will return "Refused" rather than "Unknown", which indicates to the guest that it should query other servers, so it then queries the connected DNS server, and gets the desired response. --- src/network/bridge_driver.c | 11 ++++++++--- tests/networkxml2argvdata/isolated-network.argv | 3 ++- 2 files changed, 10 insertions(+), 4 deletions(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index b8c6c97..0a60bb8 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -531,10 +531,15 @@ networkBuildDnsmasqArgv(virNetworkObjPtr network, /* If this is an isolated network, set the default route option * (3) to be empty to avoid setting a default route that's - * guaranteed to not work. + * guaranteed to not work, and set --no-resolv so that no dns + * requests are forwarded on to the dns server listed in the + * host's /etc/resolv.conf (since this could be used as a channel + * to build a connection to the outside). */ - if (network->def->forwardType == VIR_NETWORK_FORWARD_NONE) - virCommandAddArg(cmd, "--dhcp-option=3"); + if (network->def->forwardType == VIR_NETWORK_FORWARD_NONE) { + virCommandAddArgList(cmd, "--dhcp-option=3", + "--no-resolv", NULL); + } if (network->def->dns != NULL) { virNetworkDNSDefPtr dns = network->def->dns; diff --git a/tests/networkxml2argvdata/isolated-network.argv b/tests/networkxml2argvdata/isolated-network.argv index f801396..7ea2e94 100644 --- a/tests/networkxml2argvdata/isolated-network.argv +++ b/tests/networkxml2argvdata/isolated-network.argv @@ -1,5 +1,6 @@ /usr/sbin/dnsmasq --strict-order --bind-interfaces --conf-file= \ ---except-interface lo --dhcp-option=3 --listen-address 192.168.152.1 \ +--except-interface lo --dhcp-option=3 --no-resolv \ +--listen-address 192.168.152.1 \ --dhcp-range 192.168.152.2,192.168.152.254 \ --dhcp-leasefile=/var/lib/libvirt/dnsmasq/private.leases --dhcp-lease-max=253 \ --dhcp-no-override\ -- 1.7.3.4
