Permission error while adding new physical device to QEMU under libvirt? -


i'm trying add usb camera qemu can virtualized guest os. i've added following item in /etc/libvirt/qemu.conf.

cgroup_device_acl = [ "/dev/null", "/dev/full", "/dev/zero", ... "/dev/rtc", "/dev/hpet", **"/dev/video0",** ]

also, i've mounted cgroup controller below.

mkdir /dev/cgroup mount -t cgroup none /dev/cgroup -o devices

but i'm getting "permission denied" error(13) in following code.

fd = open("/dev/video0", o_rdwr | o_nonblock, 0);

strange observation error happens when use virt-manager(libvirt). issue disappears when qemu run command-line. there anyway give device access qemu in libvirt? or more step check libvirt/qemu.conf?

very long shot, did had chance go through page on libvirt docs?

it's different issue, it's being stated there, disabling selinux 1 of steps required.

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
